If you're looking for a good Database Management System (DBMS), there are plenty of options available with support for full-text indexing and searches, such as MySQL, PostgreSQL, and SQL Server. There are also external full-text search engines, such as Lucene and Solr. Let's see the advantages of using Sphinx over the DBMS's full-text searching capabilities and other external search engines:
It has a higher indexing speed. It is 50 to 100 times faster than MySQL FULLTEXT and 4 to 10 times faster than other external search engines.
It also has higher searching speed since it depends heavily on the mode, Boolean vs. phrase, and additional processing. It is up to 500 times faster than MySQL FULLTEXT in cases involving a large result set with GROUP BY. It is more than two times faster in searching than other external search engines available.
As mentioned earlier, relevancy is among the key features one expects when using a search engine, and Sphinx performs...
