There are a few terms like fields and items that have a double underline where ever they appear and when the pointer rests over them, a pop-up description appears.

 

Apparently this description is indexed by the forum software.  A website search will include a page or a forum discussion where one of the search terms appears only in the pop-up description.  The bigger problem is in going through the list of results from the search.  When the excerpt from the search result largely consists of the pop-up description, it hinders the user in finding the relevant information.

 

It would be helpful if these descriptions were excluded from an index of the website.
