REQUEST: Search Related keywords / Linked / Associated terms and tags

[AndrewBucklin]

Looking for a plugin or module for searching the VirtueMart product database that will allow the site administrator to enter search terms that should be "linked" or "associated" with other search terms.

For example, site administrator has a database with different types of "toilet tissue".  However, customers come to the site and search for "toilet paper" or "t.p." and do not see the desired results.

Looking for some plugin, module, or component that would allow the site administrator to associate "toilet paper", "t.p." and maybe other search terms or tags to the correct search term:  "toilet tissue".

Does anyone know of any such plugin / module / component?

Google does it... Example:

When doing a Google Shopping search for "toilet paper", Google automatically shows results for "toilet tissue"
