Yes, this could be a problem.

You don't want to traverse the document space if you can help 
it--that would require parsing all the documents again or keeping the 
entire link structure of the site. The latter may be useful for other 
purposes, but that could involve some serious additional storage for 
some sites.

As far as keeping a list of excluded documents, this may be the right 
way to go. Right now htmerge/htpurge completely remove all traces of 
a document if it was marked "noindex." Probably the solution is to 
leave the document (still marked "noindex") but make sure all words 
are removed from the word db. This way it would never come up in a 
search.

This is a very good point you've raised, thanks.
