Search::Xapian

Search::Xapian is an excellent software toolkit that allows developers to add advanced indexing and search facilities to their own applications. It is a Perl XS frontend to the Xapian C search library, making most features of the library available for use from Perl.

One of the greatest advantages of Xapian is its highly adaptable nature. It supports the Probabilistic Information Retrieval model as well as a rich set of boolean query operators, making it easy to tailor the search to specific needs.

Moreover, Xapian is a fast and scalable toolkit that can handle hundreds of millions of documents, making it ideal for large-scale indexing and searching projects.

To install this module, users just need to type the following:

perl Makefile.PL
make
make test
make install

Makefile.PL automatically looks for xapian-config on the PATH. However, you can also set the XAPIAN_CONFIG environmental variable to specify a path for xapian-config. Similarly, you can set the CXX environmental variable to specify a C compiler.

Overall, Search::Xapian is an incredibly powerful and efficient toolkit for advanced indexing and searching. Its scalable, adaptable and highly customizable nature makes it an indispensable tool for developers looking to enhance the search capabilities of their applications.
