It's a known bug from a few weeks ago

One that is very frustrating to me (and I am sure customers). When using advanced search you should be able to get to the second page, however, if you notice it unchecks "Message Body" so it's not searching the message body anymore so there are less results and therefore says there is no page 2.
Example: Go to the
Advance search page Put in "labview sql daq" (no quotes) in the "With all the words" line, select 10 results per page and click "GO"
There should be 15 results with the first 10 shown. When you click page 2 or "Next Page" it unchecks the message body search and searches again and finds nothing

The simple search works fine (you can get to page 2 and the last 5 results of the query above) so that is the only workaround I know for now. The issues we have been having with Advanced Search are documented and reported.
