1.9.1 problem with MatchAllDocsQuery
Hi all,
I was using lucene-1.9-rc1-dev.jar (got it from luke website I think).
I was running a query whose tostring() was:
-body:angel -body:darpa -body:protocol +MatchAllDocsQuery1.0
When I upgraded to 1.9.1, I am getting an exception:
ava.lang.ArrayIndexOutOfBoundsException: 0
at org.apache.lucene.search.MultiSearcher.rewrite(MultiSearcher.java:268)
at org.apache.lucene.search.MultiSearcher.createWeight(MultiSearcher.java:293)
at org.apache.lucene.search.Searcher.search(Searcher.java:116)
at org.apache.lucene.search.Searcher.search(Searcher.java:95)
at runner.step.LuceneSearchHelper.search(LuceneSearchHelper.java:52)
tostring gives the following:
-body:angel -body:darpa -body:protocol +MatchAllDocsQuery
is that a regression?
thanks,
javier

thanks Yonik, did not notice that. I patched my code not to run the
search in that case, previous versions of lucene did not throw any
exception in the same case though.
thanks

Hi Javier,
The exception is happening on the last line of this method:
public Query rewrite(Query original) throws IOException {
Query[] queries = new Query[searchables.length];
for (int i = 0; i < searchables.length; i++) {
queries[i] = searchables[i].rewrite(original);
}
return queries[0].combine(queries);
}
It looks like the only way that can happen is if you don't have any
searchables in your MultiSearcher.
