fix(engines): surface the official site for brand/navigational queries#87
Merged
Conversation
The lexical relevance signal scored a result zero when the query was a brand
typed without its separator ("threejs") but the title used the separator
("three.js" -> tokens three + js), demoting the official site below
single-engine forum posts that contained the bare word. Two changes fix it:
- Bridge adjacent tokens in the lexical match so "threejs" meets a "three.js"
title (concatenations are stemmed symmetrically with the query side).
- Add a bounded, exact-match navigational boost: when the squished query names
a result's registrable domain label (threejs -> threejs.org), lift it to the
top past the demotion-only blend. Short-query, exact-match only, so a
descriptive query never triggers it.
Live check: "threejs" moved threejs.org from #17 to #1.

Problem
For a brand typed without its separator (e.g.
threejs), the lexical relevance signal scored the official site zero: its titlethree.jstokenizes tothree+js, neither equal tothreejs. The demotion-only blend then sank it below single-engine forum posts that contained the literal word. Live,threejsputthreejs.orgat #17 despite two engines agreeing on it.Fix
threejsmeets athree.jstitle.threejs→ threejs.org), it is lifted to the top past the demotion-only blend. Short-query and exact-match only, so a descriptive query never triggers it. Pure on-device string work; no new requests.Verification
