There is an article written on inverted indexing 
http://hotwired.lycos.com/webmonkey/code/97/16/index2a.html

The database used is Open Source. However, it looks like it had 
Perl interfaces and the sample of the article is in Perl. Since 
SourceForge supports PHP, we may need someone to port the Perl code 
over to PHP.

I think if we use a combination of hierarchial indexes and inverted 
indexes along with issue of the context of the XML element, we 
should have a killer search/indexing capability.
