[−][src]Enum tantivy::schema::Cardinality
Express whether a field is single-value or multi-valued.
Variants
SingleValue
The document must have exactly one value associated to the document.
MultiValues
The document can have any number of values associated to the document. This is more memory and CPU expensive than the SingleValue solution.
