Query languages

Query language Where you can use it Description
Query domain-specific language (DSL) Dev Tools The primary OpenSearch query language that supports creating complex, fully customizable queries.
Dashboards Query Language (DQL) Discover and Dashboard search bar A simple text-based query language used to filter data in OpenSearch Dashboards.
Query string query language Discover and Dashboard search bar A scaled-down query language whose syntax is based on the Apache Lucene query syntax.
SQL Query Workbench A traditional query language that bridges the gap between relational database concepts and the flexibility of OpenSearch’s document-oriented data storage.
Piped Processing Language (PPL) Query Workbench The primary language used with observability in OpenSearch. PPL uses a pipe syntax that chains commands into a query.

Discover and Dashboard search bar

Using the search bar in the Discover and Dashboard apps, you can search data with the following two languages:

The following table compares DQL and query string query language features.

DQL and query string query language DQL Query string query language
  • Wildcard expressions (DQL supports * only)
    - Ranges
    - Boolean operations
    | - Querying nested fields | - Regular expressions
    - Fuzziness
    - Proximity queries
    - Boosting

By default, the query language in the Discover search toolbar is DQL. To switch to query string syntax, select DQL and then turn off OpenSearch Dashboards Query Language. The query language changes to Lucene, as shown in the following image.
