looqs - Full-text search with previews for your files

looqs is a tool that creates a full-text search index for your files. It allows you to look at previews where your search terms have been found, as shown in the screenshots below.

Goals and principles

• Find & Preview. Instead of merely telling you where your search phrase has been found, it should also render the corresponding portion/pages of the documents and highlight the searched words.
• No daemons. As some other desktop search projects are prone to have annoying daemons running that eat system resources away, this solution should make do without daemons where possible.
• Easy setup. Similiarly, there should be no need for heavy-weight databases. Instead, this solution tries to squeeze out the most from simple approaches. In particular, it relies on sqlite.
• GUI & CLI. Provide CLI interfaces and GUI interfaces
• Sandboxing. As reading and rendering lots of formats naturally opens the door for security bugs, those tasks are offloaded to small, sandboxed sub-processes to mitigate the effect of exploited vulnerabilities.

Supported platforms

Linux (on amd64) is currently the main focus. Currently, I don't plan on supporting anything else and the sandboxing architecture does not make it likely. I suppose a version without sandboxing might be conceivable for other platforms, but I have no plans or resources to actively target anything but Linux at this point.
