> FacetComponent works fine on empty fields but crashes if facet.prefix parameter is set.
> Looking at the code : getOrdTermsEnum(..) returns null if no value is found on the field but _getCounts(...)_ does not checks if _TermsEnum te_ is null or not.
> {code:java|title=UnInvertedField.java (getCounts(..))}
> TermsEnum te = getOrdTermsEnum(searcher.getAtomicReader());
> if (prefix != null && prefix.length() > 0) {
> final BytesRef prefixBr = new BytesRef(prefix);
> 232: if (te.seekCeil(prefixBr, true) == TermsEnum.SeekStatus.END) {
> startTerm = numTermsInField;
> } else {
> startTerm = (int) te.ord();
> }
> prefixBr.append(UnicodeUtil.BIG_TERM);
> if (te.seekCeil(prefixBr, true) == TermsEnum.SeekStatus.END) {
> endTerm = numTermsInField;
> } else {
> endTerm = (int) te.ord();
> }
