Summary

fix #29750

use contains_any instead of Chaining where = where | f

Screenshots

Before After
... ...
Method Line Change
search_by_vector 361 Uses contains_any(doc_ids)
search_by_full_text 408 Uses contains_any(doc_ids)

Before (problematic - deep nesting):
ors = [Filter.by_property("document_id").equal(x) for x in doc_ids]
where = ors[0]
for f in ors[1:]:
where = where | f # Creates (A | (B | (C | ...))) nesting

After (efficient - flat structure):
where = Filter.by_property("document_id").contains_any(doc_ids)

Benefits:

  • Avoids deep nesting issues with 100+ document IDs
  • Better performance (single operation vs. recursive tree evaluation)
  • Cleaner, more idiomatic Weaviate code
