Recoll is a personal full text search tool for Unix/Linux.

It is based on the very strong Xapian search engine library, for which it provides a powerful text extraction layer and a complete, yet easy to use, Qt graphical interface.

Recoll is free, open source, and licensed under the GPL. The current version is 1.17.2 (Release notes).

Recoll will index an MS-Word document stored as an attachment to an e-mail message inside a Thunderbird folder archived in a Zip file (and more...). It will also help you search for it with a friendly and powerful interface, and let you open a copy of the file without much fuss. There is little that will remain hidden on your disk. More details …

If you have problems with Recoll, documentation and support are available.

Recoll user ? Maybe there are still a few useful search tricks that you don't know about. A quick look at the search tips might prove useful ! Also the Faqs and Howtos on bitbucket.org, and some contributed result list formats.

News:

2012-05-16: Release 1.17.2 fixes a few minor bugs in 1.17. See the Release notes.
2012-04-07: we now have a Chinese user manual: Recoll现在有中文手册咯： Recoll中文手册，HTML
2012-03-27: Recoll gets a Ubuntu Unity Lens. If you are running an Ubuntu release where this makes sense, you can install the recoll-lens package from the Recoll PPA. The Lens uses the Recoll GUI as a proxy to extract and display embedded documents, which native utilities can't reach directly. And of course you still need to run the GUI (or the command line recollindex) to get the indexing going !
2012-03-24: Release 1.17 is out, see the Release notes.
2011-11-26: the result list glitch: ennoying and easily worked-around: it will sometimes happen (for a yet undetermined reason) that the result list paragraph format stored in the Qt preferences file will get garbled, causing result lists with no displayed paragraphs (the counts and pages are ok, the results can be seen in table mode, but not in list mode). The workaround is to go to
Preferences->Query configuration->User interface
and erase the result paragraph format string (^A DEL in the text area), this will reset the string to the default value.

Thanks
