Does it handle document chunking?

Yes, it provides implementation patterns for EmbeddingStoreIngestor and recursive document splitters to optimize text segments for specific LLM token limits.

Can I use this for Spring Boot projects?

Yes, it includes specific patterns for Spring @Bean configurations, service-layer integration, and health indicators compatible with Spring Boot Actuator.

What vector databases does this skill support?

This skill supports all major LangChain4j-compatible providers including PostgreSQL (pgvector), Pinecone, MongoDB Atlas, Milvus, and Neo4j.

Is there support for hybrid search?

Absolutely, the skill includes instructions for setting up EmbeddingSearchRequest with metadata-based filtering to combine vector similarity with structured data queries.
