Constructor CachingWrapperFilter
CachingWrapperFilter(Filter)
New deletes are ignored by default, which gives higher cache hit rate on reopened readers. Most of the time this is safe, because the filter will be AND'd with a Query that fully enforces deletions. If instead you need this filter to always enforce deletions, pass either RECACHE or DYNAMIC.
