# How to query in Discover's classic mode
Classic mode in **Discover** works on a [data view](https://www.elastic.co/docs/explore-analyze/find-and-organize/data-views), a definition of the data to query, usually saved, such as all your web logs. You search the data with [Kibana Query Language (KQL)](https://www.elastic.co/docs/explore-analyze/query-filter/languages/kql) or [Lucene](https://www.elastic.co/docs/explore-analyze/query-filter/languages/lucene-query-syntax), two search syntaxes, and narrow the results with filters.

## Set up and run a classic query

- [Select a data view and a time range](/docs/explore-analyze/discover/search-and-filter-classic#find-the-data-you-want-to-use) to select the data you explore.
- [Search with KQL or Lucene and narrow the results with filters](https://www.elastic.co/docs/explore-analyze/discover/search-and-filter-classic).
- Add [runtime fields](https://www.elastic.co/docs/explore-analyze/discover/add-fields-to-data-views) to your data views.
- [Switch to ES|QL mode](https://www.elastic.co/docs/explore-analyze/discover/switch-esql-mode) and see how Discover converts your search and filters into an ES|QL query.
