 ## Filter and vector queries
 
-A query request can include a vector query and a [filter expression](search-filters.md). Filters apply to text and numeric fields, and are useful for including or excluding search documents based on filter criteria. Although a vector field isn't filterable itself, you can set up a filterable text or numeric field. 
+A query request can include a vector query and a [filter expression](search-filters.md). Filters apply to text and numeric fields, and are useful for including or excluding search documents based on filter criteria. Although a vector field isn't filterable itself, you can attribute a text or numeric field in the same index as "filterable".
 
-In contrast with full text search, a filter in a pure vector query is effectively processed as a post-query operation. The set of k-NN is retrieved, and then combined with the set of filtered results. As such, the value of `"k"` predetermines the surface over which the filter is applied. For `"k": 10`, the filter is applied to 10 most similar documents. For `"k": 100`, the filter iterates over 100 documents (assuming the index contains 100 documents that are sufficiently similar to the query).

-> If you don't have source fields with text or numeric values, check for document metadata, such as LastModified or CreatedBy properties that might be useful in a filter.
