DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Search tokenizer emits compound candidates from single-character tokens

You'll notice
Useful2 Signal0
Elsewhere

Search now joins stray single-character tokens with their neighbours, so split-up terms match better.

What

Query tokenization pairs a single-character token with an adjacent multi-character neighbour and offers the joined form as an extra candidate, improving matches on terms that were split apart.

Details
  • The joined form is appended before the compound-first ordering is applied.
  • Compound candidates are still filtered out unless the caller explicitly asked for compounds.
Evidence

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
