Metadata Driven Result Reranking And Post Processing

via “generative and reranker modules for post-processing search results”

Weaviate is an open-source vector database that stores both objects and vectors, allowing for the combination of vector search with structured filtering with the fault tolerance and scalability of a cloud-native database​.

Unique: Implements module architecture where generative and reranking logic is decoupled from core search, enabling pluggable implementations for different LLM providers and reranker models. Modules receive full search context (query, results, metadata) enabling sophisticated post-processing.

vs others: More integrated than separate LLM calls because generation happens within query execution; better than Pinecone's reranking because custom reranker modules can be implemented.
