    • Method Detail

      • onUse

        void onUse​(Query query)
        Callback that is called every time that a cached filter is used. This is typically useful if the policy wants to track usage statistics in order to make decisions.
      • shouldCache

        boolean shouldCache​(Query query)
                     throws IOException
        Whether the given Query is worth caching. This method will be called by the QueryCache to know whether to cache. It will first attempt to load a DocIdSet from the cache. If it is not cached yet and this method returns true then a cache entry will be generated. Otherwise an uncached scorer will be returned.
