Related Tags
Each of the items on your results page has one or more tags. This cloud lists all the different tags associated with each item returned from your original search. Click on the ‘+’ sign next to a tag to narrow your search, on a tag itself to search on that particular term instead.
For example, if you searched on ‘medical’ and the Related Tags cloud includes ‘+ pharamaceutical’, clicking the ‘+’ will return every item tagged with both ‘medical’ and ‘pharmaceutical’.
On the other hand, clicking the word ‘pharmaceutical’ will produce a new listing of every item tagged with ‘pharmaceutical’, along with a new Related Tags tag cloud.
