Hi there, is it generally recommended to activate the "infix" search feature in order to get better accuracy for my RAG system? For my usecase, a Multi-Search with hybrid search will be conducted. One search on document-level, while the other on the chunk level. Document-level will include fields like Doc_title, doc_summary, Participants and the embedding field. Chunk-level on the other hand on fields like Chunk(around 400-600 words each), section_title, section_summary, Keywords and also Questions (list of predefined questions) However, as infix inccurs high CPU usage, does it make sense to activate infix for e.g. Chunk, Keywords and section_title or do you recommend a different approach?
