LaunchBar is a popular application launcher, clipboard manager, and much more.
HoudahSpot is a powerful file search tool. It takes the guesswork out of Spotlight searches and helps you find file hidden deep in the “haystack” of files accumulated over the years.
The “Search with HoudahSpot” LaunchBar action provides an elegant way to start a HoudahSpot search using LaunchBar.
The action accepts text input. Select the action in LaunchBar and press the space key to start entering text. The action will start a HoudahSpot search with the text. By default, HoudahSpot searches for files matching the text you have entered. The search field does allow for more complex queries. See the HoudahSpot User Guide for more details.
The action alternatively accepts a folder location. Select the action in LaunchBar and press the return key. You will be ask to select a folder. The action will open a new HoudahSpot search focussed on the selected location.
Update: HoudahSpot 5 ships with a newer version of the LaunchBar action. You can install the action from HoudahSpot > Preferences > Extensions.
