Llm Enhanced Search

LLM Enhanced Search improves Drupal Search API by using a Large Language Model (LLM) to match natural-language searches with terms from a configured taxonomy vocabulary.

Use this module when your site uses controlled taxonomy terms, but users may search using synonyms, descriptions, or everyday language instead of the exact terminology.

For example, a user searching for portable computer can have the taxonomy term Laptop automatically added to their Search API query.

Features

- Enhances Search API queries using an LLM.
- Maps natural-language searches to terms from a configurable taxonomy vocabulary.
- Validates LLM results against the configured vocabulary before adding them.
- Avoids adding terms already present in the user's query.
- Preserves other exposed filters from the Search API View.
- Leaves the original query unchanged when no valid term is identified.

Additional Requirements

- Search API
- A Search API-powered View with an exposed full-text search filter
- A configured Drupal taxonomy vocabulary
- A supported and configured LLM service

Post-Installation

Please read the README.txt for configuration steps

How It Works

The module acts as a query-enhancement layer:
User query => LLM => validated taxonomy term => enhanced Search API query => Search API results

The LLM response is validated against the configured vocabulary, so only valid taxonomy terms can be added to the search query.
