Recoll is a desktop full-text search tool.
Recoll finds keywords inside documents as well as file names.
- Versions are available for Linux and MS Windows.
- A WEB front-end with preview and download features can replace or supplement the GUI for remote use.
- It can search most document formats. You may need external applications for text extraction.
- It can reach any storage place: files, archive members, email attachments, transparently handling decompression.
- One click will open the document inside a native editor or display an even quicker text preview.
- The software is free, open source, and licensed under the GPL.
- Detailed features and application requirements for supported document types.
Recoll is based on the very capable Xapian search engine library, for which it provides a powerful text extraction layer and a complete, yet easy to use, Qt graphical interface.
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 a PDF at the right page with two clicks. There is little that will remain hidden on your disk.
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 section, and some contributed result list formats.
Thanks: Recoll borrows a lot of code from other packages, and welcomes code and ideas from contributors, see some of the Credits.
- Why I'm not happy with OpenSUSE: I just lost half an afternoon trying to get an OpenSUSE VM to update. First it failed with no disk space which was weird because it had a 16GBytes disk and nothing but the regular install and a recoll build directory. Discovered that the system was creating snapshots, had to dig to guess how to clean them them up and stop the thing. Did I ask for snapshots ? Nope. Was I informed about this interesting initiative ? Nope. Maybe some helpful suggestion when the file system got full ? Nope again. After getting rid of the snapshots, I decided to delete a few big packages I don't need: Mozilla, Libreoffice, digikam,etc, and I did it with the regular tool: zypper. Then launch "zypper update", finally ? Which begins to helpfully download the just deleted Mozillla, libreoffice, etc. This is almost as bad as win10. Bye bye OpenSUSE, a little respect for users might help.
- Version 1.23.7 fixes an ennoying bug with dir: filtering (potential missing results for directory names with upper-case characters).
- Version 1.23.6 is released to provide a workaround to the Xapian 1.4 snippets generation issue. It will create indexes with the previous 'Chert' index format by default. If your index is in 'Glass' format and you are experiencing the UI freezes, you will need to delete it, by actually running rm -rf on the directory, (typically rm -rf ~/.recoll/xapiandb) before restarting the indexing.
- PROBLEM: XAPIAN 1.4 RECOLL GUI FREEZES: we have an identified problem when running with Xapian 1.4 new Glass index format. The snippets generation can take forever, which results in an apparent GUI freeze while displaying the result list. I am working on finding a solution. Meanwhile, you can work around the issue by disabling snippets generation. Uncheck: Preferences->GUI configuration->Search parameters->Dynamically build abstracts. Also, if you have an index created by Xapian 1.2, avoid deleting it completely (rm -rf xapiandb). Prefer recollindex -z which will preserve the index format. This affects all newer Linux releases: Debian Stretch and derivatives, OpenSUSE Tumbleweed, probably recent Fedora, but not the current Ubuntu LTS, Xenial, which has Xapian 1.2. Recoll for MS-Windows is also not affected.
- Release 1.23.5 has a few changes and fixes and supports the (still experimental) new version of the Web browser extension. Also, I split the Debian/Ubuntu packages into command-line/GUI parts (recollcmd/recollgui), with a top recoll packages which depends on both, and this causes conflicts during the upgrade. For upgrading, either first delete the recoll package, then upgrade and reinstall recoll, or fix the issues with apt -f upgrade
- Finalizing the move to the new site, I am closing the old BitBucket project. The existing BitBucket issues have been archived.
- The source code repository and issue
tracker are moving to a
- Release 1.23.2 has gotten much better at processing PDF XMP data.
- I experimented with installing the Recoll Web UI with Apache, and found out that this is really easy, actually both easier to set up and more useful than running it standalone. Recently added: instructions for running with Nginx instead of Apache.
MS-Windows. Still a few things missing (like
real-time monitoring), but it does work, and it has a proper
installer, so you can easily get rid of it if you don't like
it. Have a look..
This is an almost-native port, based on Qt and the Windows
API, no need for Cygwin. Thanks to Christian Motz for
helping with the filter interface (and the rest). I would
love some feedback!
- The aspell command used for orthographic suggestions is broken on Debian Jessie (because of an aspell packaging issue), and this will not be fixed for the Debian release. See the simple workaround here.
- A nice new application to complement Recoll: recollfs implements a Fuse filesystem where Recoll queries are represented as directories, the contents of which are links to the result documents.
- While working on a Recoll-Mutt interface I discovered incidentally that the Recoll Webui Web interface works quite well with the links web browser inside a terminal window. This appears to be an interesting solution for people looking for a search interface usable in a non-GUI environment.
- Thanks to some of its users, Recoll now has filters to index and retrieve Lotus Notes messages (some implementation notes from an early user), and there is also now a Web browser interface for querying your Recoll indexes.
- A problem with a simple workaround has caused
several reported recollindex
crashes recently (for 1.17). If you store and index
Mozilla/Thunderbird email out of the standard location
(~/.thunderbird), you should add the following at the end of
your configuration file (e.g.:
[/path/to/my/mozilla/mail] mhmboxquirks = tbirdAdjust the path to your local value of course... Without this hint, recollindex has trouble finding the message delimiters inside the folder files, and will possibly use all the computer's memory and crash. Apart from crashes, which only occur for very big folders, this also causes incorrect mail indexing.
- A new user-contributed script for those who use real-time indexing on laptops: stop or start indexing according to AC power status. See the details on the Wiki.
