To speed up quicksearches, limit the search by product or component. Add “comp: <string>” to your query to limit it to components whose names contain that string. As an abbreviation, you can simply use “:” instead of “comp:”, although that also searches in products whose names which contain the string.
By analogy with the use of “:”, there are abbreviations for some other common fields as well.
