The new Full Text Search (FTS) capabilities in Couchbase Mobile 2.0 enable natural language querying, allowing users to search for documents containing specific terms or phrases within the document's content. FTS is based on N1QL, Couchbase's declarative query language that extends SQL for JSON. The FTS interface allows users to create indexes and construct queries using a Query Builder interface, which simplifies the process of building complex queries. Stemming, stemming, and locale-specific natural language querying are supported, enabling users to search for documents containing specific terms or phrases in various languages. The FTS capabilities can be used to perform searches on multiple properties, including stop words, wildcard expressions, and ranking. While the FTS capabilities are powerful, there are limitations, including a limited match expression structure and no support for custom language tokenizers, fuzzy search, faceted search, or server-side database implementations. Future releases will evaluate these limitations and add more functionality to the FTS capabilities.
