# SCORE Lexical Search

### High-speed, fuzzy autocomplete and exact match search powered by Apache Solr.

**SCORE Lexical Search** indexes content, media, and taxonomy into unified Apache Solr cores. Using the Search API, STD.DEV enables direct HTTP/REST querying from Genkit or frontends, offering lightning-fast exact text resolution, URL routing, and fallback autocomplete suggestions without requiring full Drupal bootstraps.

### High-Speed Indexing

Powered by Apache Solr, the lexical search engine continuously indexes content, media, and taxonomy terms into highly optimized cores. This ensures that massive datasets remain instantly searchable with exact-match precision and advanced fuzzy logic.

### Autocomplete & URL Routing

The service provides lightning-fast autocomplete suggestions for frontends without requiring a full Drupal bootstrap. Additionally, it can directly resolve lexical queries into exact URL routes, drastically reducing time-to-first-byte (TTFB) for search navigations.

### Headless REST APIs

Exposed seamlessly through the Drupal Search API, the Solr engine provides secure HTTP/REST endpoints. This allows any decoupled client application to execute complex search parameters and aggregations autonomously.

### Deterministic AI Routing

Lexical Search is exposed as a primary tool for the SCORE Genkit microservice. The AI agent dynamically evaluates user intent, actively choosing to route queries to Solr when a task requires precise, deterministic keyword and entity matching rather than broad semantic similarity.

#### Q: What are the benefits of using Apache Solr for the lexical search engine?

Apache Solr ensures that massive datasets remain instantly searchable with exact-match precision and advanced fuzzy logic due to its continuous indexing into highly optimized cores.

#### Q: How does the autocomplete feature improve frontend performance?

The service provides lightning-fast autocomplete suggestions for frontends without requiring a full Drupal bootstrap.

#### Q: Can SCORE Lexical Search directly map search queries to specific URLs?

Yes, it can directly resolve lexical queries into exact URL routes, significantly reducing time-to-first-byte for search navigations.

#### Q: What kind of API access does the Solr engine provide for decoupled applications?

The Solr engine provides secure HTTP/REST endpoints exposed through the Drupal Search API, enabling decoupled client applications to execute complex search parameters and aggregations autonomously.

#### Q: How does SCORE Genkit utilize Lexical Search for AI agents?

Lexical Search is a primary tool for the SCORE Genkit microservice, where the AI agent dynamically evaluates user intent and routes queries to Solr for tasks requiring precise keyword and entity matching.

#### Q: When does the AI agent choose to route queries to Solr instead of using semantic similarity?

The AI agent routes queries to Solr when a task requires precise, deterministic keyword and entity matching, as opposed to broad semantic similarity.

#### Q: What is the primary purpose of SCORE Lexical Search?

SCORE Lexical Search indexes content, media, and taxonomy into unified Apache Solr cores to enable fast, precise searching and routing.

#### Q: What kind of search capabilities does SCORE Lexical Search offer beyond exact matches?

SCORE Lexical Search offers advanced fuzzy logic in addition to exact-match precision for searching massive datasets.

#### Q: What is the advantage of not requiring a full Drupal bootstrap for autocomplete?

Not requiring a full Drupal bootstrap allows for lightning-fast autocomplete suggestions.

#### Q: How does SCORE Lexical Search reduce Time-To-First-Byte (TTFB)?

It drastically reduces TTFB for search navigations by directly resolving lexical queries into exact URL routes.

#### Q: What does SCORE Lexical Search index into Apache Solr cores?

SCORE Lexical Search indexes content, media, and taxonomy terms into highly optimized Apache Solr cores.
