Method BuildMatchExpression

Namespace

Assembly

Qavren.Edge.VectorData.dll

BuildMatchExpression(ICollection<string>, KeywordCombinator, string?)

Quotes each keyword as an FTS5 string literal, doubling any embedded quote, and joins them. Quoting is what makes FTS5 treat a token as a phrase, so AND, OR, NOT, NEAR, *, ^, : and parentheses inside a keyword are inert rather than operators. This is the package's one injection surface.
