Searching JSON: compare text search in Couchbase and MongoDB.

The text explores the importance of incorporating robust search capabilities in app design, highlighting the challenge of varying text search functionalities across different databases like MySQL, NoSQL, MongoDB, and Couchbase. It discusses the need for applications to use the best text search features available, noting that while simple searches can be efficiently handled by B-Tree indexes, more complex searches require advanced methods like inverted indexes. The text compares MongoDB's B-Tree based text search, which is limited in functionality and performance, with Couchbase's more comprehensive Full-Text Search (FTS) powered by Bleve, which offers extensive capabilities for natural-language querying and supports a wider range of data types and query options. This comparison is illustrated through examples and performance metrics, emphasizing Couchbase's superior efficiency and flexibility in handling complex search queries.
