Hi, I am implementing dynamic faceting as described here - http://www.norconex.com/facets-with-lucene/ and running into trouble for multi value facets. For strings this is not a problem. One can use SortedSetDocValuesFacetField when indexing the values for faceting and SortedSetDocValuesFacetCounts for the actual facet query. This way I can add multiple values for the same field.
When it comes to numbers I use NumericDocValuesField for indexing and LongRangeFacetCounts for faceting This works for single valued fields, but I cannot add multiple numeric values as with SortedSetDocValuesFacetField. If I try to add multiple NumericDocValuesField I get an excption during indexing. Changing to a SortedNumericDocValuesField, I can add mutliple numeric values during index time, but then I get an exception when using LongRangeFacetCounts. Is there a reason why dynamic faceting does not work for multi value numeric fields? Is this a limitation of the Lucene engine or would it be possible in general? Is there a potential workaround? Any help appreciated, Hardy --------------------------------------------------------------------- To unsubscribe, e-mail: java-user-unsubscr...@lucene.apache.org For additional commands, e-mail: java-user-h...@lucene.apache.org
