Description
Adds support for per-query field boost directives in the lexical search syntax. Users can now include bracket expressions (e.g.,
upload [metadata^20]orupload [metadata+10, title-5]) in their search queries to dynamically adjust how much weight individual fields contribute to scoring for that specific query.Supported operator formats within
[...]blocks:^N— multiply the field's base weight by N=N— set the field weight to an absolute value+/++/+++— increment weight by the number of+characters-/--/---— decrement weight by the number of-characters+N/-N— add or subtract a numeric valueField aliases are supported (e.g.,
title→name,desc→description,impl→implementation,input/output→io,meta→metadata).Phrase bonuses are scaled proportionally to the adjusted field weights, keeping scoring consistent. Boost blocks are stripped from the query text before token parsing so they do not interfere with term matching.

Test Instructions
npm test(or equivalent) and confirm the new"supports per-query field boosts in bracket directives"test passes alongside existing lexical search tests.upload [metadata^20]and verify that results with matching metadata rank above results that only match on name/title.Additional Comments
The field weight overrides are scoped entirely to the parsed query and do not mutate the global
FIELD_WEIGHTSconstant.
