Hi,
after an upgrade from solr-1.3 to 1.4.1 we're getting an
ArrayIndexOutOfBoundsException for a query with rows=0 and a sort
param specified:
java.lang.ArrayIndexOutOfBoundsException: 0

org.apache.lucene.search.FieldComparator$StringOrdValComparator.copy(FieldComparator.java:660)

at
org.apache.solr.handler.RequestHandlerBase.handleRequest(RequestHandlerBase.java:131)
at org.apache.solr.core.SolrCore.execute(SolrCore.java:1316)
The query is e.g.:
/select/?sort=popularity+desc&rows=0&start=0&q=foo
When this is changed to rows=1 or when the sort param is removed the
exception is gone and everything's fine.
With a clean 1.4.1 installation (unzipped, started example and posted
two documents as described in the tutorial) this issue is not
reproducable.
Does anyone have a clue what might be the reason for this and how we
could fix this on the solr side?
Of course - for a quick fix - I'll change our app so that there's no
sort param specified when rows=0.
Thanx && cheers,
Martin
