Not Query Usageedit

A query that filters out matched documents using a query.

Deprecated in 2.1.0. Use the bool query with must_not clause instead.

See the Elasticsearch documentation on not query for more details.

.Not(c => c
    .Name("named_query")
    .Boost(1.1)
    .Filters(
        qq => qq.MatchAll(m => m.Name("query1")),
        qq => qq.MatchAll(m => m.Name("query2"))
    )
)
