Improve your Spotlight searches with search operators
If you know the file type of a document you are looking for, you can pre-qualify search results by using operators within Spotlight. As you can see in the screenshot, I pre-qualified my search for ‘asia’ with the PDF filetype operator, which led Spotlight to only search PDF documents for the search term. You can even use date sensitive search operators, to search for files created or edited between, before, after, or on specific dates! This makes finding things even faster and more precise, so try them out yourself. Here’s a few example operators to enter before your search query:

Note that all of these search operators are used in Spotlight in the following syntax format:
kind:audio Rolling
kind:application
kind:pdf
kind:jpeg
kind:word
kind:folder
kind:image
kind:audio
date:today
date:yesterday

date:>10/1/09 will find any file modified after November 1, 2009, note that the dates you enter must correspond to the short date format you have set in your International preferences
date:<12/31/09 will find any file modified before December 31, 2009
date:1/1/06-12/31/09 will find files modified between the two specified dates. Example syntax is:
date:1/1/06-12/31/09 contract

Thank you; it’s very helpful to find information like this, which isn’t officially “manualized.” It would be especially helpful (and most likely profitable) to publish some manuals, at different levels (e.g., some people just want to get their email and be done, while others are really interested in how the system works, and how things are implemented, so they can make he most of the computing power they have available. Anyway, your work here was most useful!
