Summary Result Storage And Retrieval With Document History

via “advanced document indexing with multi-vector and parent-document retrieval”

Everything you need to know to build your own RAG application

Unique: Decouples retrieval granularity (summaries) from context granularity (full documents) using MultiVectorRetriever and parent-child mappings, enabling precise relevance matching without losing contextual information

vs others: More effective than chunk-based retrieval for long documents because it retrieves at the document level while scoring at the summary level, reducing context fragmentation
