Enum tantivy_query_grammar::Occur

source · [−]

pub enum Occur {
    Should,
    Must,
    MustNot,
}

Expand description

Defines whether a term in a query must be present, should be present or must be not present.

Variants

`Should`

For a given document to be considered for scoring, at least one of the document with the Should or the Must Occur constraint must be within the document.

`Must`

Document without the term are excluded from the search.

`MustNot`

Document that contain the term are excluded from the search.
