By default,
max_chunk_size_tokens
is set to 800 andchunk_overlap_tokens
is set to 400, meaning every file is indexed by being split up into 800-token chunks, with 400-token overlap between consecutive chunks.You can adjust this by setting chunking_strategy when adding files to the vector store. There are certain limitations to chunking_strategy:
max_chunk_size_tokens
must be between 100 and 4096 inclusive.chunk_overlap_tokens must
be non-negative and should not exceedmax_chunk_size_tokens
