> Because of LUCENE-5833 we have to do merge the _:suggest_ field values in one
> single valued field, however in case there's only one text value for
> suggestions (e.g. a Lucene property index on _jcr:primaryType_) the value is
> not stored as {{LuceneIndexEditor}} uses the previously set field
> {{newPropertyField(FieldNames.SUGGEST, value, true, false)}} instead of
> {{FieldFactory.newSuggestField(f.stringValue())}} causing the building of the
> suggester dictionary to fail with:
> {noformat}
> org.apache.jackrabbit.oak.plugins.index.lucene.util.SuggestHelper could not
> update the suggester
> java.lang.IllegalArgumentException: need at least one suggestion
