I presume by saying "subdirectory" you're referring to filesystem
directories and you're indexing a directory tree of files. If you
index the path (perhaps relative from the root is best) as a keyword
field (untokenized, but indexed) you could perform filtering on a /
path/subpath sort of way using PrefixQuery.
As for paragraphs - how you index a "document" is entirely
application dependent. Maybe it makes sense to parse the documents
before handing them to Lucene such that you're creating a Lucene
Document for each paragraph rather than for each entire file.
Slicing the granularity of a domain into Documents is a fascinating
topic :)

I'm new to Lucene and was wondering what is the best way to perform
a search on a subdirectory or subdirectories within the index? My
thought at this point is to build a query to first search for files
in the required directory(ies) and then use that query to make a
QueryFilter and use that QueryFilter in the actual search. Is
there an easier way?
On an unrelated note, does anybody know of a way to get results a
the section level within a document? For example, could I find not
just a document that matches my query, but the paragraph within
that document that best matches the query?
thanks,
John
