Xapian是一个用C++编写的全文检索程序，他的作用类似于Java的lucene。尽管在Java世界lucene已经是标准的全文检索程序，但是C/C++世界并没有相应的工具，而Xapian则填补了这个缺憾。



Xapian的api和检索原理和lucene在很多方面都很相似，但是也有一些地方存在不同，具体请看Xapian自己的文档:http://www.xapian.org/docs/



Xapian除了提供原生的C++编程接口之外，还提供了Perl，PHP，Python和Ruby编程接口和相应的类库，所以你可以直接从自己喜欢的脚本编程语言当中使用Xapian进行全文检索了。-Xapian is an Open Source Search Engine Library, released under the GPL. It s written in C++, with bindings to allow use from Perl, Python, PHP, Java, Tcl, C# and Ruby (so far!)



Xapian is a highly adaptable toolkit which allows developers to easily add advanced indexing and search facilities to their own applications. It supports the Probabilistic Information Retrieval model and also supports a rich set of boolean query operators.



If you re after a packaged search engine for your website, you should take a look at Omega: an application we supply built upon Xapian. Unlike most other website search solutions, Xapian s versatility allows you to extend Omega to meet your needs as they grow.
