Enum MatchSearchModifier 

pub enum MatchSearchModifier {
    NaturalLanguage,
    NaturalLanguageQueryExpansion,
    Boolean,
    QueryExpansion,
}

The optional search modifier of a MySQL StringFunc::MatchAgainst — one of the four documented full-text combinations. WITH QUERY EXPANSION combines only with the (implicit or explicit) natural-language mode; IN BOOLEAN MODE WITH QUERY EXPANSION parse-rejects (engine-verified).

Variants

NaturalLanguage

IN NATURAL LANGUAGE MODE.

NaturalLanguageQueryExpansion

IN NATURAL LANGUAGE MODE WITH QUERY EXPANSION.

Boolean

IN BOOLEAN MODE.

QueryExpansion

WITH QUERY EXPANSION.
