Newest Version of MongoDB Includes Text Search
April 6, 2013
Some welcome enhancements to MongoDB are included in the open-source data base’s latest release, we learn from “MongoDB 2.4 Can Now Search Text,” posted at the H Open. The ability to search text indexes has been one of the most requested features, and the indexing supports 14 languages (or no language at all.) The write-up supplies this handy link to a discussion of techniques for creating and searching text indexes.
The post describes a second feature of MongoDB 2.4, the hashed index and sharding:
“Hash-based sharding allows data and CPU load to be spread well between distributed database nodes in a simple to implement way. The developers recommend it for cases of randomly accessed documents or unpredictable access patterns. New Geospatial indexes with support for GeoJSON and spherical geometry allow for 2dsphere indexing; this, in turn, offers better spherical queries and can store points, lines and polygons.”
There is also a new modular authentication system, though its availability is limited so far. The project has also: added support for fixed sized arrays in documents; optimized counting performance in the execution engine; and added a working set size analyzer. See the article for more details, or see the release notes, which include upgrade instructions. The newest version can be downloaded here.
