# {{esql}} Search functions [esql-search-functions]
|
||
|
|
|
||
|
|
Use these functions for [full-text search](docs-content://solutions/search/full-text.md) and [semantic search](docs-content://solutions/search/semantic-search/semantic-search-semantic-text.md).
|
||
|
|
|
||
|
|
Get started with {{esql}} for search use cases with our [hands-on tutorial](docs-content://solutions/search/esql-search-tutorial.md).
|
||
|
|
|
||
|
|
Full text functions can be used to match [multivalued fields](/reference/query-languages/esql/esql-multivalued-fields.md). A multivalued field that contains a value that matches a full text query is considered to match the query.
|
||
|
|
|
||
|
|
Full text functions are significantly more performant for text search use cases on large data sets than using pattern matching or regular expressions with `LIKE` or `RLIKE`
|
||
|
|
|
||
|
|
See [full text search limitations](/reference/query-languages/esql/limitations.md#esql-limitations-full-text-search) for information on the limitations of full text search.
