is it possible to convert a query like "un lis" to "un* lis*"

Thanks in advance for your answer.
Cheers
Michael

For addition
You could break the input stream up and construct
a BooleanQuery from a series of PrefixQuerys, but
there's nothing automatic that I know of.

Hi,
You can subclass QueryParser and override newFieldQuery to produce a
PrefixQuery instead of TermQuery - that's all. Here a simple example with an
anonymous inner class:
qp = new QueryParser(...) {
@Override
protected Query newTermQuery(Term term) {
return new PrefixQuery(term);
}
};

was NearRealTime, i reopened taxwriter and refreshed the taxreader every
3min.
day one, OK
day two, OK
day tree, no more indexing, results were only from the previou
Hi,
I know that we need to delete/index a document in order to update any part of
it,
but recently we need to index a field which changes rather frequently so that
each
time reindexing whole document would be inpractical for performance reason.
This field is a small integer so I may just trea
So, I thought you're response meant that I could eliminate my code:
String[] fields = new String[1];
fields[0] = "EVERYTHING"; // use the single "big" field in the
index
mlt.setFieldNames(fields);
But, if I comment out that code, my unit test fails. If I include

Yes, this is totally unrelated to fields[].
it has to do with which fieldname is passed to the analyzer to
analyze the reader into tokens (and there can be only one for thi
