Searching for content using the current SharePoint 2003 Server can be a nightmare. In SharePoint 2010 and SharePoint Online the Search functionality has been greatly improved and it is also now possible to use query terms in your search criteria to refine the results returned. You can use terms such as >,>=, < , <=, and <> along with some other built in terms, for example, Write, Size and Author. This means that you could use a search string like this, Write>=”9/1/2011”, which would return all documents modified since the beginning of this month (September). This can be very handy when there is a large amount of content available on a SharePoint Site and you know some of the details about the document. You can also join multiple queries together to even further narrow your search results. More details on this topic can be found here.
