solr caches from external caching system like memcached

Hi, Is it possible to use solr caches such as query cache , filter cache and document cache from external caching system like memcached as it has several advantages such as centralized caching system and reducing the pause time of JVM 's garbage collection as we can assign less memo

score computation for dismax handler

Hi , When query is made across multiple fields in dismax handler using paramater qf , I have observed that with debug query enabled the resultant score is max score of scores of query across each fields . but I want the resultant score to be sum of score across fields (like the standard ha

understanding how solr/lucene handles a select query (to analyze where solr/lucene is taking time )

Hi, As mentioned in my previous post , we are experiencing a delay (latency ) for 15 % of the request to solr . delay is about 2-4 sec sometimes it even reaches 10 sec (noticed from apache tomcat logs where solr is running

tracking solr response time

Hi, We are using solr for many of ur products it is doing quite well . But since no of hits are becoming high we are experiencing latency in certain requests ,about 15% of our requests are suffering a latency . We are trying to identify the problem . It may be due to network issue or sol
