I'm using FacetedSearcher and have a MultiValueFacet that has over 1024 values. Searching causes TooManyClauses exception with following stacktrace:

Caused by: org.apache.lucene.search.BooleanQuery$TooManyClauses: maxClauseCount is set to 1024

It might not be a best practise to use that many values in a facet but as this is handled in LuceneIndexSearcherImpl it should be handled here also.
