Recoll
Recoll is a personal full text indexing package for Linux and other Unix
systems.
Recoll is based on a very strong backend (Xapian), for which it provides
an easy to use, feature-rich, zero-administration interface.
Recoll is free and copyrighted under the GPL license, see COPYING inside
the distribution. A lot of the code is imported from other packages, see
the Credits.
Features:
* Document types: text, html, pdf (with pdftotext), postscript (with
ghostscript's pstotext), msword (with antiword), openoffice files,
maildir and mailbox mail folders (Mozilla and thunderbird mail ok).
Deals with compressed versions of same.
* Relatively powerful query facilities, with boolean searches, phrases,
filter on file types and directory tree.
* Support for multiple charsets. Internal processing and storage uses
Unicode UTF-8.
* Stemming performed at query time (can switch stemming language after
indexing)
* Easy installation. No database daemon, web server or exotic language
necessary. The idea is that everybody should index their files because
it makes life easier.
* GUI based on qt, written with qt Designer.
* An indexer which runs either as a thread inside the GUI or as an
external, cron'able program.
Recoll has been compiled and tested on FreeBSD, Linux and Solaris
(versions FreeBSD 5.3, Redhat 7.3, Solaris 8, but other not too distant
releases should be ok too). You can download the source code here.
Things lacking, coming in the not too far future:
* An interactive configuration tool. You need to edit files by hand for
now.
* Packages, rpm or other. It's all tar files currently.
* Documentation and help.
* Translations for the user interface.
* A few more filters for less common file types.
I very much welcome suggestions or (gasp) code.
In hope that this can be useful to somebody, it already is for me.

Credits
Recoll borrows (steals?) heavily from the following projects. I tried to
include the relevant copyright attributions with the code. Any omission is
unintentional and will be fixed as soon as notified.
* Xapian: The database module (core) is used unmodified, and quite a lot
of code has been borrowed from Omega, the web-based search application
(ie: the html parser, plus miscellaneous bits and ideas).
* Estraier: Miscellaneous pieces of code and ideas, especially for
charset handling, and code from external filters.
* Unac: for accent removal. This is a relatively small package, not that
easy to find, it has been integrated almost unmodified in the Recoll
package.
* Iconv, for character set conversion.
* Binc IMAP for MIME parsing code.
* I fear the rest of the bugs to be mostly mine:

Using Recoll
Indexation
By default, Recoll will index your home directory. If you want to change
this, you need to edit the configuration file ($HOME/.recoll/recoll.conf).
Follow the comments in the file to adjust the parameters.
Indexing is performed either by starting the recollindex program, or by
the indexing thread inside the recoll program (use the File menu).
Simple search
Enter search term(s) in the text field at the top left. Clicking the
Search button or hitting the Enter key will start a search. By default,
this will look for documents with any of the terms (the ones with more
terms will get better scores). Use the Advanced search dialog for other
kinds of searches
A list of results will be displayed in the main list window. Clicking on
an entry will open an internal preview window for the document.
Double-clicking will attempt to start an external viewer (have a look at
the ~/.recoll/mimeconf file to see how these are configured).
Search tips, shortcuts
Entering a capitalized word in any search field will prevent stem
expansion (example: Recoll will not look for gardening if you enter Garden
instead of garden).
A phrase can be looked for by enclosing it in double quotes. Example:
"user manual" will look only for occurrences of user immediately followed
by manual.
Entering ^Q almost anywhere will close the application.
Entering ^W in a preview tab will close it (and, for the last tab, close
the preview window).
Complex/advanced search
The advanced search dialog has fields that will allow a more refined
search, looking for documents with all given words, a given exact phrase,
or none of the given words (all fields may be combined by a default AND
clause).
It will let you search for documents of specific mime types (ie: only
text/plain, or text/html or application/pdf etc...)
It will let you restrict the search results to a subtree of the indexed
area.
In other respects, it works as the simple search.
