Yeah, these classes are a bit weird in that they are configured via
properties, and not setters. They really are designed to run inside
the benchmaker and not much attention was paid to using them elsewhere.
However, one can co-opt them for the purposes you are doing:
Something like:
TrecDocMaker docMaker = new TrecDocMaker();
Properties properties = new Properties();
....
properties.setProperty("doc.maker.forever", "false");
...
docMaker.setConfig(new Config(properties));
(not I was using the EnWikiDocMaker in the above example, but it
should work for Trec, too.
I often also do something like:
while ((doc = docMaker.makeDocument()) != null && i < numDocs) {
...
where numDocs is the max. docs I want.

Greetings,
I am trying to use TrecDocMaker so I can successfully index and
evaluate
lucene on a TReC collection.
It seems like I would just repeatedly call makeDocument() until all
the
Documents have been created, but makeDocument appears to just read
forever.
In general TrecDocMaker seems like an odd class and I just cant
figure out
how to use it right. I have been changing the class so it works
with an
uncompressed collection and trying to modify it so makeDocument doesnt
endlessly read, but no matter what I have done it is just causing a
different error. Clearly I am trying too hard.
In short what I want know is how am I supposed to use TrecDocMaker
to parse
my collection...cause the current Lucene implementation doesnt seem
to work
right, or I am using it wrong.
Thanks
Dana
