From KDE Apps:

Version 1.10.2 of Recoll, a KDE front-end for the Xapian text searching engine, has been released. Changes:

• 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" connfiguration variable to allow explicitely restricting the file types which do get indexed.

Screenshots here, downloads (source, packages for Fedora, Mandriva, Debian, Ubuntu and Solaris) here. Requires Qt 3.3 or 4 and a recent version of Xapian.
