However, this does not necessarily reflect > how much a filter is used. For instance you can call cache and not use the > filter, or call cache once and then use it a hundred times. It would be more > useful to know how many times a filter has been used on a top level reader, > and I think we can do this by doing something like below in the caching > wrapper filter? > {code} > @Override > public DocIdSet getDocIdSet(LeafReaderContext context, Bits acceptDocs) > throws IOException { > if (context.ord == 0) { > // increment counter > } > } > {code} -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
