However, it is dif An aggregate query groups search results by specified column values and then counts the number of records in each group. For example, an aggregate query in which a location column is specified counts the number of records per location. Making a graph from the result of an aggregate query against a date column is an easy way to visualize changes over time. Also, a combination of refinement by location and an aggregate query against a date column allows visualization of changes over time in specific location.

For example, a database can receive read queries through the built-in HTTP server of groonga while accepting update queries through MySQL. +A database of Groonga can be shared with multiple threads/processes. Also, multiple threads/processes can execute read queries in parallel even when another thread/process is executing an update query because Groonga uses read lock-free data structures. This feature is suited to a real-time application that needs to update a database while executing read queries. In addition, Groonga allows you to build flexible systems. For example, a database can receive read queries through the built-in HTTP server of Groonga while accepting update queries through MySQL. Geo-location (latitude and longitude) search -------------------------------------------- Location services are getting more convenient because of mobile devices with GPS. For example, if you are going to have lunch or dinner at a nearby restaurant, a local search service for restaurants may be very useful, and for such services, fast geo-location search is becoming more important. -Groonga provides inverted index-based fast geo-location search, which supports a query to find points in a rectangle or circle. Groonga gives high priority to points near the center of an area. Also, groonga supports distance measurement and you can sort points by distance from any point. +Groonga provides inverted index-based fast geo-location search, which supports a query to find points in a rectangle or circle.

Groonga library --------------- -The basic functions of groonga are provided in a C library and any application can use groonga as a full text search engine or a column-oriented database. Also, libraries for languages other than C/C++, such as Ruby, are provided in related projects. See `related projects <http://groonga.org/related-projects.html>`_ for details. +The basic functions of Groonga are provided in a C library and any application can use Groonga as a full text search engine or a column-oriented database.

Groonga server -------------- -Groonga provides a built-in server command which supports HTTP, the memcached binary protocol and the groonga query transfer protocol (gqtp). Also, a groonga server supports query caching, which significantly reduces response time for repeated read queries. Using this command, groonga is available even on a server that does not allow you to install new libraries. +Groonga provides a built-in server command which supports HTTP, the memcached binary protocol and the Groonga query transfer protocol (gqtp).

Groonga storage engine ---------------------- -Groonga works not only as an independent column-oriented DBMS but also as storage engines of well-known DBMSs. For example, `mroonga <http://mroonga.org/>`_ is a MySQL pluggable storage engine using groonga. By using mroonga, you can use groonga for column-oriented storage and full text search. A combination of a built-in storage engine, MyISAM or InnoDB, and a groonga-based full text search engine is also available. All the combinations have good and bad points and the best one depends on the application. See `related projects <http://groonga.org/related-projects.html>`_ for details. +Groonga works not only as an independent column-oriented DBMS but also as storage engines of well-known DBMSs.
