> Currently the basic indexing filter includes inbound anchor text for a given URL in the
index.  This sometimes allows pages to show up in search results where they may not be relevant.
 An example of this is a search for "dallas hotels" in our production index (www.visvo.com).
 Google would show up first in this example although there is no text matching either dallas
or hotels on the google home page.  What is happening here is there are inlinks into google
with the words dallas and hotels which get included in the index for google.com and because
google would have a very high boost due to inlinks, google shows up first for these search
terms.  I propose we add an option to allow/prevent inlink anchor text from being included
in the index and set the default for this option to NOT include inbound link anchor text.
