Sphinx Description

Free open-source SQL full-text search engine Sphinx is a full-text search engine, distributed under GPL version 2. Commercial license is also available for embedded useGenerally, it's a standalone search engine, meant to provide fast, size-efficient and relevant fulltext search functions to other applications. Sphinx was specially designed to integrate well with SQL databases and scripting languages. Currently built-in data sources come with support for fetching data either via direct connection to PostgreSQL or MySQL, or using XML pipe mechanism (a pipe to indexer in special XML-based format which Sphinx recognizes).As for the name, Sphinx is an acronym which is officially decoded as SQL Phrase Index.Sphinx distribution includes the following programs:· indexer: an utility to create fulltext indices;· search: a simple (test) utility to query fulltext indices from command line;· searchd: a daemon to search through fulltext indices from external software (Web scripts using Sphinx API; or MySQL with SphinxSE; or your application server);· sphinxapi: a set of API libraries for popular Web scripting languages (there are native API ports for PHP, Python, Java, Perl, and Ruby). Here are some key features of "Sphinx": · high indexing speed (upto 10 MB/sec on modern CPUs) · high search speed (avg query is under 0.1 sec on 2-4 GB text collections) · high scalability (upto 100 GB of text, upto 100 M documents on a single CPU) · supports distributed searching (since v.0.9.6) · supports MySQL natively (MyISAM and InnoDB tables are both supported) · supports phrase searching · supports phrase proximity ranking, providing good relevance · supports English and Russian stemming · supports any number of document fields (weights can be changed on the fly) · supports document groups · supports stopwords · supports different search modes ("match all", "match phrase" and "match any" as of v.0.9.5) · generic XML interface which greatly simplifies custom integration · pure-PHP (ie. NO module compiling etc) search client API
