Houdah Software (http://www.houdah.com/) has updated HoudahSpot, their Spotlight front end for Mac OS X, to version 3.1. It now supports the legacy type and creator codes

In version 3.1, the text preview of source code now bypasses the Spotlight engine. HoudahSpot may now reveal multiple items at once in Finder or PathFinder. And the app now highlights the selected criterion rows.

Tags are non-hierarchical keywords assigned to files. They serve a similar purpose than folders. The crucial difference being that a file may be assigned several tags and be located by any of them.

HoudahSpot’s tagging feature is based upon the OpenMeta technology, so is compatible with a growing number of third party tagging applications. The HoudahSpot Tray lists favorite tags as well as tags recently used by HoudahSpot or another OpenMeta tagging solution. Drag a file to a tag to assign it that tag. Drag a file to the file well to be presented with a window to enter any number of tags. Select tags and double-click to start a search. Hold down the option key while double-clicking to match any of the selected tags.

HoudahSpot is a Spotlight front-end for Mac OS X 10.5 (“Leopard”) and 10.6 (“Snow Leopard”). With it, users may create detailed queries to pinpoint the exact file they want to get to.

HoudahSpot 3.1 costs US$30 for a single-user license. It’s a $5 update for registered users and a free update for registered users of version 3.0.
