-------------------------------------
I respectfully disagree. IMHO, inlink anchor text is one of the most
descriptive things about a page. If inlink anchor text has too much noise as
you suggest, then we must work on eliminating this noise, I don't think that
'disabling' it is the answer. Some ideas:
* We may try reducing inlink text importance (by readjusting its boost).
* We may ignore inlink anchor text if inlink anchor text and parse text is
completely unrelated, i.e none of the words actually appear on the page (I
think google does something similar to avoid google bombs).
* We may ignore inlink text from untrusted sites/low-score sites.
> 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.
