Recoll

Recoll – free and open source software for full-text search of files by content, as well as by file names

Review

• Qt GUI, WEB, command line, Gnome Shell Search Plugin, Unity Scope, Dolphin KIO and krunner interfaces;
• Searches most common document types, emails and their attachments. Transparently handles decompression (zip, gzip, bzip2, etc.);
• Powerful query facilities, with boolean searches, phrases, proximity, wildcards, filter on file types and directory tree, accessible through the query language or a GUI query builder interface;
• Multi-language and multi-character set with Unicode based internals;
• Extensive documentation, with a complete user manual and man pages for each command;
• Can use a Firefox extension to index visited Web pages history. See the Howto for more detail;
• Processes all email attachments, and more generally any realistic level of container imbrication (the “msword attachment to a message inside a mailbox in a zip” thingy…​);
• Multiple selectable databases;
• Support for multiple charsets. Internal processing and storage uses Unicode UTF-8;
• Stemming performed at query time (can switch stemming language after indexing);
• An indexer which can be set to run either as a batch, cron’able program, or, on Unix-like systems, as a real-time indexing daemon;
• It is possible to carry out indexing on a schedule;
• It is possible to save / load search queries;
• Support for light and dark themes;
• Has a customizable interface;
• Full screen support.
