Words in index

[gustavoh10]

I'm devoloping an application that searches in several XML files
that in index using zend lucene.

The idea is simple I have a simple index structure that
store the title of the file (field titulo), the name (field nombre_archivo),
the category (field categoria) and all the words
presents in the document (field contents).

When I open the index created with lucene, using lukeall-0.7.1, I see all
the
words I index order by Rank

Anyone knows any function that I can use to get those words stored in the
index to
manage in php?

thanks
