TTL rows never removed from Index

[grom358]

If you insert rows using TTL after the TTL expires it is never removed from the Lucene index. If you query with JMX the number of documents, it is still there. Also tried force merge of segments and refreshing index but none of these operations would remove the expired documents from the Lucene index even though they no longer existed in the base table. The only way I found to remove them was to rebuild the index with nodetool rebuild_index
