Overview ¶
Package queryterm holds the query-side vocabulary rules that both ways of searching this graph have to agree on: the full-text query built for the database, and the term list the fallback scan matches nodes against. A word dropped by one and kept by the other makes the two tools disagree about what the searcher asked for.

Functions ¶
func DropFunctionWords ¶
DropFunctionWords removes meaningless words from a query's terms, and gives up when that would leave nothing. @intent stop one unremarkable English word from deciding which results a query returns. @domainRule a query made only of function words keeps every term, so it stays answerable.
func IsFunctionWord ¶
IsFunctionWord reports whether a term is one of the meaningless words. @intent let a caller judge one term without copying the list.
func IsNaturalLanguage ¶ added in v0.14.0
IsNaturalLanguage reports whether a query should retrieve documents by any meaningful term and let shared scoring combine the evidence.
Two or three code terms are normally a partially remembered identifier and retain strict all-term matching. Prose either announces itself with a question word or contains more than three meaningful terms. The count happens after function-word removal so "get user by id" remains the compact identifier-shaped query "get user id". @intent choose soft retrieval only for sentence-shaped queries while preserving precise identifier lookup. @domainRule compact queries of at most three meaningful terms remain strict unless their grammar explicitly asks a question.
