Recoll

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

It is based on the very strong Xapian backend.

It provides an easy to use, feature-rich interface with a Qt GUI.

Most common document types are supported are supported along with their compressed versions (Text, HTML, PDF, Dvi, PostScript, Openoffice, Lyx, Scribus, Word/Excel/PPT, Abiword, Kword, Wordperfect, RTF, djvu, gaim logs, maildir and mailbox mail folders including attachments, misc media files).

Powerful query facilities are provided from simple keyword entry to assisted boolean query building with proximity clauses, filtering on file types or location.

Multiple character sets are supported. Internal processing and storage uses Unicode UTF-8.

Recoll has few dependancies. No database daemon, Web server, or exotic language/framework is necessary. Installation is easy.

Indexing can be performed in batch mode or in real time.

Thanks to Xapian, indexing does not tax system resources excessively and searching is very fast.

Release 1.13.00: new class of filters and indexed file types: zip, chm, ics. Improved big text files handling, Firefox visited pages indexing. Quite a few other performance and usability improvements.

Release 1.12.3: Bug fixes
Release 1.12: new KDE KIO slave module, collapsing of identical results, context-sensitive F1 help, saving email attachments and other embedded documents to files, and other small improvements and bug fixes.

Release 1.11: easy filtering of results by document type, nicer previews which use html when possible, python programming interface for indexing and searching, better support for the Xesam user query language, new filter framework, better support for arbitrary field indexing and searching.

Release 1.10:
- Created mailing-list to improve support. Check home page.
- Fixed openSuse 11 compile issues.
- Fixed bug in interpreting email mime structure, which resulted in base-64 decoding errors.
- Fixed "Prev" button in preview window. Would actually go forward when walking the search terms.
- Allow setting the highlight color for search terms in result list and preview
- Added svg filter
- Ensure that in case the data of a file can't be indexed because of some error, at least the file name is indexed.
- Improve query language to support OR queries of terms with field specifications (ie: title:someterm OR author:someauthor).
- Fix filename search to split patterns on white space, so that a "*.jpg *.jpeg" search does what's expected. Means you now need to use double-quotes if there is actual embedded white space.
- Jump directly to the external editor choice dialog instead of opening preferences when an external viewer is not found.
- Allow stopping indexing through menu action (only works with qt4 for now).
- Create an "indexedmimetypes" configuration variable to allow explicitely restricting the file types which do get indexed.
- Adds support for CJK text, and a GUI configuration tool for the main configuration file.

Release 1.9: This release brings a number of small practical improvements: new filters: Wordperfect, Abiword, Kword, jpeg, flac, ogg; better control of disk and memory usage during indexing; improved abstract generation; arbitrary field support; improved qt4 support; and miscellaneous user interface improvements and bug fixes, described in more detail in the Changes file.

Release 1.8: a small query language with some field-based searches (author, title, etc.), and wildcard handling: the standard *, ?, [] wildcard charactgers can be used in any search. The release also includes a number of small user interface improvements and bug fixes.
