Definition
Attribute-Based Filtering is the application of deterministic logical constraints on structured metadata fields within a vector database to narrow the candidate pool before or during a similarity search. This ensures that retrieved context strictly adheres to required parameters such as date ranges, document ownership, or category tags, preventing the model from accessing irrelevant or unauthorized data.
Filtering by structured metadata tags (e.g., 'Author: Smith') versus semantic similarity searching by meaning.
"A security gate at a library that only allows books from a specific genre or publication year to be placed on the librarian's desk for final review."
