Third party API ports and plugins exist for Perl, C#, Haskell, Ruby-on-Rails, and possibly other languages and frameworks.
Starting version 1.10-beta, Sphinx supports two different indexing backends: "disk" index backend, and "realtime" (RT) index backend.
For instance, one might need to sort news search results by date and then relevance, or search through products within specified price range, or limit blog search to posts made by selected users, or group results by month.
To do that efficiently, Sphinx allows to attach a number of additional to each document, and store their values in the full-text index.
Sphinx is a full-text search engine, publicly distributed under GPL version 2. It was specially designed to integrate well with SQL databases storing the data, and to be easily accessed scripting languages.
Technically, Sphinx is a standalone software package provides fast and relevant full-text search functionality to client applications.
Depending on what source Sphinx should get the data from, different code is required to fetch the data and prepare it for indexing. At the time of this writing, there are drivers for My SQL and Postgre SQL databases, which can connect to the database using its native C/C API, run queries and fetch the data.
There's also a driver called xmlpipe, which runs a specified command and reads the data from its .
Sphinx development was started back in 2001, because I didn't manage to find an acceptable search solution (for a database driven Web site) which would meet my requirements.
However, Sphinx does not depend on nor require any specific database to function.
Applications can access Sphinx search daemon (searchd) using any of the three different access methods: a) via native search API (Sphinx API), b) via Sphinx own implementation of My SQL network protocol (using a small SQL subset called Sphinx QL), or c) via My SQL server with a pluggable storage engine (Sphinx SE).
Built-in sources can fetch data directly from My SQL, Postgre SQL, ODBC compliant database (MS SQL, Oracle, etc), or a pipe in a custom XML format. to natively support other DBMSes) is designed to be as easy as possible.
RT indexes, as of 1.10-beta, can only be populated using Sphinx QL.As a quick hack, you can edit sphinx.h and replace off_t with DWORD in a typedef for Sph Offset_t, but note that this will prohibit you from using full-text indexes larger than 2 GB.
