-------------------------------------

Honestly, i don't think not indexing anchor words that do not appear in the web 
site text is not a wise solution. What made google so successful is indexing 
anchor text + PR, the classic example being that, the page 
http://www.honda.com/ never mentions that Honda is a car manufacturer, but the 
anchor text does.   

That said, I think we should focus on finding a way to eliminate the noise on 
anchor text. At this point we take the first 10K links and discard the others, 
due to size constraints. But a better way would be to select the best ones, or 
select the most frequent words, etc. 




> Including inlink anchor text in index can create irrelevant search results.

> 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.
