Este artigo tem muitas informações úteis sobre como maximizar o poder da pesquisa do Spotlight . Para pesquisar por data, por exemplo:
Check the Date Looking for a file that was created during a specific time period? Spotlight has a handle on dates. Typing date:today will bring up files you created, read, received, or opened today. You can also use the date: keyword with yesterday and tomorrow (for the latter, Spotlight restricts its results to iCal events and to-do items).
The latest version of Spotlight also lets you specify more parameters (whether a file was created or modified on a certain date), as well as enter an exact date or a range of dates. For example, you can type created:12/25/07 to find files authored on that date; type modified:<11/30/06 to look for files changed before that date; or type created:1/1/06-12/31/06 to locate files created between these two dates. Unfortunately, date: keywords don’t seem to work correctly all the time.
