I started writing a module to read lucene indexes but didn't get very 
far - a number of implementation features (variable-length integers so 
you need to read them a single byte at a time, lengths in characters 
instead of bytes so you can't just skip over a block that you want to 
ignore) make them annoying to deal with in their normal form (although 
I'm sure it makes alot of sense for the java implementation).  If you 
ignore some of those encoding oddities but use the same basic 
architecture of named fields to search within that might be a reasonable 
foundation to start building on.
