# Find the structure of a text file

Authentication: required

Availability: Generally available since 7.13

## Paths

- `POST` `/_text_structure/find_structure`

## Description

The text file must contain data that is suitable to be ingested into Elasticsearch.

This API provides a starting point for ingesting data into Elasticsearch in a format that is suitable for subsequent use with other Elastic Stack functionality.
Unlike other Elasticsearch endpoints, the data that is posted to this endpoint does not need to be UTF-8 encoded and in JSON format.
It must, however, be text; binary text formats are not currently supported.
The size is limited to the Elasticsearch HTTP receive buffer size, which defaults to 100 Mb.

The response from the API contains:

* A couple of messages from the beginning of the text.
* Statistics that reveal the most common values for all fields detected within the text and basic numeric statistics for numeric fields.
* Information about the structure of the text, which is useful when you write ingest configurations to index it or similarly formatted text.
* Appropriate mappings for an Elasticsearch index, which you could use to ingest the text.

All this information can be calculated by the structure finder with no guidance.
However, you can optionally override some of the decisions about the text structure by specifying one or more query parameters.

## Required privileges

- Cluster privileges: `monitor_text_structure`

## Query string parameters

- `charset` (string) — optional
  The text's character set.
It must be a character set that is supported by the JVM that Elasticsearch uses.
For example, `UTF-8`, `UTF-16LE`, `windows-1252`, or `EUC-JP`.
If this parameter is not specified, the structure finder chooses an appropriate character set.
- `column_names` (string) — optional
  If you have set format to `delimited`, you can specify the column names in a comma-separated list.
If this parameter is not specified, the structure finder uses the column names from the header row of the text.
If the text does not have a header role, columns are named "column1", "column2", "column3", for example.
- `delimiter` (string) — optional
  If you have set `format` to `delimited`, you can specify the character used to delimit the values in each row.
Only a single character is supported; the delimiter cannot have multiple characters.
By default, the API considers the following possibilities: comma, tab, semi-colon, and pipe (`|`).
In this default scenario, all rows must have the same number of fields for the delimited format to be detected.
If you specify a delimiter, up to 10% of the rows can have a different number of columns than the first row.
- `ecs_compatibility` (string · default: disabled) — optional
  The mode of compatibility with ECS compliant Grok patterns.
Use this parameter to specify whether to use ECS Grok patterns instead of legacy ones when the structure finder creates a Grok pattern.
Valid values are `disabled` and `v1`.
This setting primarily has an impact when a whole message Grok pattern such as `%{CATALINALOG}` matches the input.
If the structure finder identifies a common structure but has no idea of meaning then generic field names such as `path`, `ipaddress`, `field1`, and `field2` are used in the `grok_pattern` output, with the intention that a user who knows the meanings rename these fields before using it.
- `explain` (boolean · default: false) — optional
  If this parameter is set to `true`, the response includes a field named explanation, which is an array of strings that indicate how the structure finder produced its result.
If the structure finder produces unexpected results for some text, use this query parameter to help you determine why the returned structure was chosen.
- `format` (enum) — optional
  The high level structure of the text.
Valid values are `ndjson`, `xml`, `delimited`, and `semi_structured_text`.
By default, the API chooses the format.
In this default scenario, all rows must have the same number of fields for a delimited format to be detected.
If the format is set to `delimited` and the delimiter is not set, however, the API tolerates up to 5% of rows that have a different number of columns than the first row.
  Values: `ndjson`, `xml`, `delimited`, `semi_structured_text`
- `grok_pattern` (string) — optional
  If you have set `format` to `semi_structured_text`, you can specify a Grok pattern that is used to extract fields from every message in the text.
The name of the timestamp field in the Grok pattern must match what is specified in the `timestamp_field` parameter.
If that parameter is not specified, the name of the timestamp field in the Grok pattern must match "timestamp".
If `grok_pattern` is not specified, the structure finder creates a Grok pattern.
- `has_header_row` (boolean) — optional
  If you have set `format` to `delimited`, you can use this parameter to indicate whether the column names are in the first row of the text.
If this parameter is not specified, the structure finder guesses based on the similarity of the first row of the text to other rows.
- `line_merge_size_limit` (number · default: 10000) — optional
  The maximum number of characters in a message when lines are merged to form messages while analyzing semi-structured text.
If you have extremely long messages you may need to increase this, but be aware that this may lead to very long processing times if the way to group lines into messages is misdetected.
- `lines_to_sample` (number · default: 1000) — optional
  The number of lines to include in the structural analysis, starting from the beginning of the text.
The minimum is 2.
If the value of this parameter is greater than the number of lines in the text, the analysis proceeds (as long as there are at least two lines in the text) for all of the lines.

NOTE: The number of lines and the variation of the lines affects the speed of the analysis.
For example, if you upload text where the first 1000 lines are all variations on the same message, the analysis will find more commonality than would be seen with a bigger sample.
If possible, however, it is more efficient to upload sample text with more variety in the first 1000 lines than to request analysis of 100000 lines to achieve some variety.
- `quote` (string) — optional
  If you have set `format` to `delimited`, you can specify the character used to quote the values in each row if they contain newlines or the delimiter character.
Only a single character is supported.
If this parameter is not specified, the default value is a double quote (`"`).
If your delimited text format does not use quoting, a workaround is to set this argument to a character that does not appear anywhere in the sample.
- `should_trim_fields` (boolean) — optional
  If you have set `format` to `delimited`, you can specify whether values between delimiters should have whitespace trimmed from them.
If this parameter is not specified and the delimiter is pipe (`|`), the default value is `true`.
Otherwise, the default value is `false`.
- `timeout` (union oneOf · default: 25s) — optional
  The maximum amount of time that the structure analysis can take.
If the analysis is still running when the timeout expires then it will be stopped.
  Values: `-1`, `0`
- `timestamp_field` (string) — optional
  The name of the field that contains the primary timestamp of each record in the text.
In particular, if the text were ingested into an index, this is the field that would be used to populate the `@timestamp` field.

If the `format` is `semi_structured_text`, this field must match the name of the appropriate extraction in the `grok_pattern`.
Therefore, for semi-structured text, it is best not to specify this parameter unless `grok_pattern` is also specified.

For structured text, if you specify this parameter, the field must exist within the text.

If this parameter is not specified, the structure finder makes a decision about which field (if any) is the primary timestamp field.
For structured text, it is not compulsory to have a timestamp in the text.
- `timestamp_format` (string) — optional
  The Java time format of the timestamp field in the text.

Only a subset of Java time format letter groups are supported:

* `a`
* `d`
* `dd`
* `EEE`
* `EEEE`
* `H`
* `HH`
* `h`
* `M`
* `MM`
* `MMM`
* `MMMM`
* `mm`
* `ss`
* `XX`
* `XXX`
* `yy`
* `yyyy`
* `zzz`

Additionally `S` letter groups (fractional seconds) of length one to nine are supported providing they occur after `ss` and separated from the `ss` by a `.`, `,` or `:`.
Spacing and punctuation is also permitted with the exception of `?`, newline and carriage return, together with literal text enclosed in single quotes.
For example, `MM/dd HH.mm.ss,SSSSSS 'in' yyyy` is a valid override format.

One valuable use case for this parameter is when the format is semi-structured text, there are multiple timestamp formats in the text, and you know which format corresponds to the primary timestamp, but you do not want to specify the full `grok_pattern`.
Another is when the timestamp format is one that the structure finder does not consider by default.

If this parameter is not specified, the structure finder chooses the best format from a built-in set.

If the special value `null` is specified the structure finder will not look for a primary timestamp in the text.
When the format is semi-structured text this will result in the structure finder treating the text as single-line messages.

      A variant of text that trades scoring and efficiency of positional queries for space efficiency. This field
effectively stores data the same way as a text field that only indexes documents (index_options: docs) and
disables norms (norms: false). Term queries perform as fast if not faster as on text fields, however queries
that need positions such as the match_phrase query perform slower as they need to look at the _source document
to verify whether a phrase matches. All queries return constant scores that are equal to 1.0.

      - `dims` (number)
        Number of vector dimensions. Can't exceed `4096`. If `dims` is not specified, it will be set to the length of
the first vector added to the field.
      - `element_type` (enum · default: float)
        The data type used to encode vectors. The supported data types are `float` (default), `byte`, and `bit`.

Supported values include:
  - `bit`: Indexes a single bit per dimension. Useful for very high-dimensional vectors or models that specifically support
bit vectors.

NOTE: when using `bit`, the number of dimensions must be a multiple of `8` and must represent the number of bits.
  - `byte`: Indexes a 1-byte integer value per dimension.
  - `float`: Indexes a 4-byte floating-point value per dimension.
        Values: `bit`, `byte`, `float`

        If `true`, you can search this field using the kNN search API.
      - `index_options` (object)
        An optional section that configures the kNN indexing algorithm. The HNSW algorithm has two internal parameters
that influence how the data structure is built. These can be adjusted to improve the accuracy of results, at the
expense of slower indexing speed.

This parameter can only be specified when `index` is `true`.
        - `confidence_interval` (number)
          The confidence interval to use when quantizing the vectors. Can be any value between and including `0.90` and
`1.0` or exactly `0`. When the value is `0`, this indicates that dynamic quantiles should be calculated for
optimized quantization. When between `0.90` and `1.0`, this value restricts the values used when calculating
the quantization thresholds.

For example, a value of `0.95` will only use the middle `95%` of the values when calculating the quantization
thresholds (e.g. the highest and lowest `2.5%` of values will be ignored).

Defaults to `1/(dims + 1)` for `int8` quantized vectors and `0` for `int4` for dynamic quantile calculation.

Only applicable to `int8_hnsw`, `int4_hnsw`, `int8_flat`, and `int4_flat` index types.
        - `ef_construction` (number · default: 100)
          The number of candidates to track while assembling the list of nearest neighbors for each new node.

Only applicable to `hnsw`, `int8_hnsw`, `bbq_hnsw`, and `int4_hnsw` index types.
        - `m` (number · default: 16)
          The number of neighbors each node will be connected to in the HNSW graph.

Only applicable to `hnsw`, `int8_hnsw`, `bbq_hnsw`, and `int4_hnsw` index types.
        - `type` (enum)
          The type of kNN algorithm to use.

Supported values include:
  - `bbq_flat`: This utilizes a brute-force search algorithm in addition to automatically quantizing to binary vectors.
Only supports `element_type` of `float`.
  - `bbq_hnsw`: This utilizes the HNSW algorithm in addition to automatic binary quantization for scalable approximate kNN
search with `element_type` of `float`.

This can reduce the memory footprint by nearly 32x at the cost of some accuracy.
  - `flat`: This utilizes a brute-force search algorithm for exact kNN search. This supports all `element_type` values.
  - `hnsw`: This utilizes the HNSW algorithm for scalable approximate kNN search. This supports all `element_type` values.
  - `int4_flat`: This utilizes a brute-force search algorithm in addition to automatically half-byte scalar quantization.
Only supports `element_type` of `float`.
  - `int4_hnsw`: This utilizes the HNSW algorithm in addition to automatically scalar quantization for scalable approximate kNN
search with `element_type` of `float`.

This can reduce the memory footprint by 8x at the cost of some accuracy.
  - `int8_flat`: This utilizes a brute-force search algorithm in addition to automatically scalar quantization. Only supports
`element_type` of `float`.
  - `int8_hnsw`: The default index type for `float` vectors. This utilizes the HNSW algorithm in addition to automatically scalar
quantization for scalable approximate kNN search with `element_type` of `float`.

This can reduce the memory footprint by 4x at the cost of some accuracy.
          Values: `bbq_flat`, `bbq_hnsw`, `flat`, `hnsw`, `int4_flat`, `int4_hnsw`, `int8_flat`, `int8_hnsw`
      - `similarity` (enum)
        The vector similarity metric to use in kNN search.

Documents are ranked by their vector field's similarity to the query vector. The `_score` of each document will
be derived from the similarity, in a way that ensures scores are positive and that a larger score corresponds
to a higher ranking.

Defaults to `l2_norm` when `element_type` is `bit` otherwise defaults to `cosine`.

`bit` vectors only support `l2_norm` as their similarity metric.

This parameter can only be specified when `index` is `true`.

Supported values include:
  - `cosine`: Computes the cosine similarity. During indexing Elasticsearch automatically normalizes vectors with `cosine`
similarity to unit length. This allows to internally use `dot_product` for computing similarity, which is more
efficient. Original un-normalized vectors can be still accessed through scripts.

The document `_score` is computed as `(1 + cosine(query, vector)) / 2`.

The `cosine` similarity does not allow vectors with zero magnitude, since cosine is not defined in this case.
  - `dot_product`: Computes the dot product of two unit vectors. This option provides an optimized way to perform cosine similarity.
The constraints and computed score are defined by `element_type`.

When `element_type` is `float`, all vectors must be unit length, including both document and query vectors.

The document `_score` is computed as `(1 + dot_product(query, vector)) / 2`.

When `element_type` is `byte`, all vectors must have the same length including both document and query vectors or
results will be inaccurate.

The document `_score` is computed as `0.5 + (dot_product(query, vector) / (32768 * dims))` where `dims` is the
number of dimensions per vector.
  - `l2_norm`: Computes similarity based on the `L2` distance (also known as Euclidean distance) between the vectors.

The document `_score` is computed as `1 / (1 + l2_norm(query, vector)^2)`.

For `bit` vectors, instead of using `l2_norm`, the `hamming` distance between the vectors is used.

The `_score` transformation is `(numBits - hamming(a, b)) / numBits`.
  - `max_inner_product`: Computes the maximum inner product of two vectors. This is similar to `dot_product`, but doesn't require vectors
to be normalized. This means that each vector’s magnitude can significantly effect the score.

The document `_score` is adjusted to prevent negative values. For `max_inner_product` values `< 0`, the `_score`
is `1 / (1 + -1 * max_inner_product(query, vector))`. For non-negative `max_inner_product` results the `_score`
is calculated `max_inner_product(query, vector) + 1`.
        Values: `cosine`, `dot_product`, `l2_norm`, `max_inner_product`
