# Search functions

Rightsline accepts several functions when performing a search request to the API that give the user great power to filter the results to the exact records they are looking for.  

* [Single query functions](/search/search-functions/single-query-functions.md)
* [Multi-query functions](/search/search-functions/multi-query-functions.md)
* [Join functions](/search/search-functions/join-functions.md)

The schema for all of the search functions for the 3 categories listed above can be found below.
