I was wondering if it\'s possible to exclude target folder from eclipse quick search :
Ctrl+Shift+R
Mark the "target" folders as "derived" resource from the properties screen of those folders (this option is next to read only and archive property).
In the quick search (Ctrl+Shift+R) screen press the arrow in the top right corner and untick "Show derived resources".
Then those target-files will not be considered in the quick search anymore.
