Note

Adds docs for vector index storedValues and index hints, updates HTTP API schema, and notes new/related optimizer rules across 3.12 and 4.0.

• Vector indexes (docs):
  • Introduce and explain storedValues (v3.12.7), its purpose for filtering, limits, and example with execution plan annotation (/* covered by storedValues */).
  • Note filtering handled by use-vector-index in v3.12.6 and that push-filter-into-enumerate-near (v3.12.7) now handles vector index filtering.
  • Add indexHint/forceIndexHint support for vector indexes with example.
• HTTP API:
  • Extend vector index schema to include storedValues (array of attribute paths) for both 3.12 and 4.0 docs.
• Release notes:
  • Add optimizer rule push-filter-into-enumerate-near (v3.12.7) and reference filtering handling notes.
