# Search term rules

The **Search Term Rules** feature is designed to refine searches by adjusting word terms and their usage. Various options are provided to enhance search accuracy, including the addition, modification, or exclusion of specific terms, as well as the ability to ignore certain words.

The **Search Term Rules** feature can be found in the Sidebar menu under the **Discovery** section.

The feature includes the following functionalities:

* [**Thesaurus**](/docs/discovery/search-term-rules/thesaurus.md): Set up rules for synonyms (high similarity words) and antonyms (low similarity words).
* [**Preprocessor**](/docs/discovery/search-term-rules/preprocessor.md): Set up rules for replacing words or expressions with predefined alternatives.
* [**Stop words**](/docs/discovery/search-term-rules/stop-words.md): Manage a curated list of words that are excluded from search queries.
* [**Trash**](/docs/discovery/search-term-rules/trash.md): Exclude (blacklist) results for a given search term.
