Motivation and Context (Why the change? What's the scenario?)
When importing chat messages or running tests with small files or without IDs, the storage might fill up with duplicate chunks of text that affect the number of tokens used when generating an answer.
High level description (Approach, Design)
When using the ASK API, after fetching N records from storage, discard duplicates and use only unique chunks in the RAG prompt.
The behavior is configurable via
SearchClientConfig.IncludeDuplicateFacts
and request contextcustom_rag_include_duplicate_facts_bool
arg.
