: I don't have all my facets values used by my documents, but I would like to : index theses facets values even if they returned 0 documents.
field faceting builds the list of constraints based on the indexed values found in the field -- if you don't index it, it doesn't know about it. if you want to have field facet constraints returned even though they aren't in any "real" docs, you need to index at least one "fake" doc containing all ofthose values ... then just make sure you exclude that doc at query time using an appended "fq" (you could do it by id, or some special field, whatever is easiest for you). as long as you use "facet.mincount=0" the values will still be retunred as constraints even if no documents in your results match them -Hoss
