Supported Queries

      With Full Text Search you can perform queries on Full Text Indexes. You can perform the queries either by using Couchbase Web Console, the Couchbase REST API, N1QL (using search functions in the Query service), or the Couchbase SDK.

      Query-Specification Options

      Full Text Search allows a range of query options. These include:

      • Input-text and target-text can be analyzed: this transforms input-text into token-streams, according to different specified criteria, so allowing richer and more finely controlled forms of text-matching.

      • The fuzziness of a query can be specified so that the scope of matches can be constrained to a particular level of exactitude. A high degree of fuzziness means that a large number of partial matches may be returned.

      • Multiple queries can be specified for simultaneous processing, with one given a higher boost than another, so ensuring that its results are returned at the top of the set.

      • Regular expressions and wildcards can be used in text-specification for search-input.

      • Compound queries can be designed, such that appropriate conjunction or disjunction of the total result-set can be returned.

      For information on how to execute queries, see Searching from the UI.
