PR Description

• Fixes exact search behavior:

  • Ensures that exact: true matches only when the entire property value (not just a token/word) matches the search term, case-insensitively.
  • This prevents partial/token matches (e.g., "First Note.md" will not match "first" with exact: true).

• Distinguishes between property-value and token-level exactness:

  • exact: true → matches the whole property value.
  • exactToken: true → matches individual tokens/words exactly.

• Adds/clarifies documentation and code comments:

  • Clearly explains the difference between exact and exactToken in both code and types.

• How this solves the issue:

  • Users searching with exact: true now get results only when the property value is an exact match, as expected.
  • No more false positives from partial/token matches.
