Thread:Project:Support desk/best option for multilingual full text search engine with easy to integrate.

We are planning to build a mediawiki based private multilingual wiki (need user name and password to login)site for our researching team members, with about 15k pages, it is very dynamic (content is constantly updated), we are looking for a better way to improve the search function in our private wiki. We would like the full text search function and can return a more accurate and relevant result.

what is the best option for a full text search engine (multilingual), and easy to integrate with mediawiki.
