Description

An IRC user asked about the error "64 bit numeric collapse fields are not supported" when doing a query like this where subTitle is a TextField...

fq={!collapse+field%3DsubTitle}

The code in question looks roughly like this...

if (collapseFieldType instanceof StrField) {
   ...
}  else if (collapseFieldType instanceof TrieIntField ||
              collapseFieldType instanceof TrieFloatField) {
   ...
} else {
   throw new IOException("64 bit numeric collapse fields are not supported");
}
