Combined Fields Usage
editCombined Fields Usage
editThe combined_fields query supports searching multiple text fields as if their contents had been indexed into one combined field. It takes a
term-centric view of the query: first it analyzes the query string into individual terms, then looks for each term in any of the fields.
See the Elasticsearch documentation on combined fields query for more details.
Fluent DSL example
editq
.CombinedFields(c => c
.Fields(f => f.Field(p => p.Description).Field("myOtherField"))
.Query("hello world")
.Boost(1.1)
.Operator(Operator.Or)
.MinimumShouldMatch("2")
.ZeroTermsQuery(ZeroTermsQuery.All)
.Name("combined_fields")
.AutoGenerateSynonymsPhraseQuery(false)
)
Object Initializer syntax example
editnew CombinedFieldsQuery
{
Fields = Field<Project>(p => p.Description).And("myOtherField"),
Query = "hello world",
Boost = 1.1,
Operator = Operator.Or,
MinimumShouldMatch = "2",
ZeroTermsQuery = ZeroTermsQuery.All,
Name = "combined_fields",
AutoGenerateSynonymsPhraseQuery = false
}
Example json output.
