I think you will find this is just a bug that was
fixed a while ago and your problem will disappear
if you upgrade.

Or perhaps the problem has to do with Terence Parr mentioned here:
http://www.jguru.com/forums/view.jsp?EID=749636

Maybe he can contribute his enhancement...

This error no longer occurs in the latest daily build (lucene-20020411.jar).

I should have checked first.

Thanks,

Subject: Proper use of Lucene?


I want to know if this is supposed to be a legal thing to do with lucene:

I indexed some files into index 1 that had fields x, y, and z.

I indexed some files into a index 2 that had fields x, y, q.

I used a multisearcher on the two indexes, and search for things like

q:term

So far, this all works. However, if I search for

q:ter*

lucene throws an exception. Specifically:
Opening index:
/people/medinf1/projects/vocabulary/CNI/test/prototype/index...done
Opening index:
/people/medinf1/projects/vocabulary/CNI/test/prototype/index2...done
Enter query: q:mit*

at edu.mayo.mir.cni.search.SearchTest.main(SearchTest.java:175)

Should I be able to do this?
If so, I'll grab a copy of the newest release of lucene (I'm using 1.2 beta
1 now I think) and see if it still happens. I'll try to write up a self
contained bug test too, but I'm not sure I'll be able to do that for a
couple of days.

Thanks,

Dan
