Thanks a lot Hoss
The question is when I get Spans, I get start/end positions and a
Document order (starting from 0), not the Document object itself from
which I could get a filename. Since I believe there is no way to get a
Document object from Spans, and there is no such thing as Document ID
in Lucene (right?) I attempt to have the same order for
Hits and for Spans (the indexing order) and retrieve Document for each
Spans this way.
I will try to prepare a test case. It works so far but I am afraid it
will be unstable.
Best regards
Boris

When dealing with a Hits instance, documents are iterated over in
"results
order" -- which may be by score, or may be by some other sort you've
specified.
When dealing with a Spans instance, i believe the matches are
iterated
over in index order. Besides the perofrmance reasosn why this may
be true, you also have to keep in mind that the Spans instance has
no
idea what ordering you may have used when you executed your search
-- even
if it assumed you sorted by score, the SpanQuery may have been a
part of a
much larger more complicated query in which the final scores were
vastly
different.
If i've missunderstood your problem, could you plee post a JUnit
test case
that builds a small index in a RAMDIrectory, with some code that
demonstrates what you expect to happen, and how it fails?
