How do I search for a file with "my search text" and of a certain filetype? Reading the docs, it seems I need to use the keyword "in" but how to I specify the filetype? E.g, if I want to find all excel files with the word "business" should I specify: "in business .xls" ? What if I have multiple keywords?
Sorry for such a dumb question but between spotlight and alfred there are enough differences that aren't made clear in the doc.
