When performing searches on Google I often find it helpful to narrow the results based on when the pages were indexed by Google.  This is helpful in situations where the results for your keywords are returning a lot of old pages with dated information, but you’re looking for new information pertaining to the subject.  Google provides the options to search for recent pages through their advanced search options.  To see the options available you can click the “Advanced search” link beside the search box, click the “Date, usage rights, numeric range, and more” link, and change the “Date” option.  The options currently available are past 24 hours, past week, past month, past year.

Using the advanced search works, but it takes a few clicks to get to and doesn’t have many options for the date range.   I’ve found it’s quicker and more flexible to just add a query string parameter to the end of the URL after you search for your keywords.  [more]

&tbs=rltm:1 real time results
&tbs=qdr:s past second
&tbs=qdr:n past minute
&tbs=qdr:h past hour
&tbs=qdr:d past day (24 hours)
&tbs=qdr:w past week
&tbs=qdr:m past month
&tbs=qdr:y past year

In addition to those basic parameters you can also add an integer after the “qdr” unit values to specify a specific number.  For example “&tbs=qdr:w2” will only return pages discovered by Google within the last 2 weeks.  Here is what your URL would look like in that case: http://www.google.com/#sclient=psy&hl=en&q=conetrix&tbs=qdr:w2
