Hi, I would like to find out, is the cache in the Solr cleared when I shut down the Solr instant and restart it? I am suspecting that the cache is not entirely cleared, because when I try to do a search on the same query as I did before the search, it still has a return QTime that is much faster

Re: Is Solr cache cleared when I restart Solr?

Thanks Erick and Shawn for your reply. We have recently upgraded the server RAM from 64MB to 192MB, and I noticed that this caching occurs after we upgraded the RAM. Previously, the cache may not even be preserved in the same Solr session. So is it true that the upgrading of the server RAM

Re: optimize cache-hit-ratio of filter- and query-result-cache

y gets used for the _exact_ same query with a different rows parameter. And it doesn't store the full result set, just the size configured in solrconfig.xml. Mikhail was pointing you to the admin>>core>>plugins/stats>>cache>> page. You can fire your alternate queries and filt

Thanks. The statements on http://wiki.apache.org/solr/SolrCaching#showItems are not explicitly enough for my question.

optimize cache-hit-ratio of filter- and query-result-cache

Hi, some of my solr indices have a low cache-hit-ratio. 1 Does sorting the parts of a single filter-query have impact on filter-cache- and query-result-cache-hit-ratio? 1.1 Example: fq=field1:(2 or 3 or 1) to fq=field1:(1 or 2 or 3) -> if 1,2,3 are randomly sorted 2 Does sorting the pa

Hi, I'm trying to import my data from an sql database using the dataimporthandler. For some nested entity I want to use the cache to cache the result of my stored procedure. My config looks like this > > > > >cacheLookup="product

Re: Use dataimporthandler cache with stored procedures

Hello Jean-Philippe, You either call it 300 times with the different param value, without cache or load all rows once and cache them SQL examples in the doc explain this clear, I suppose. On Wed, Nov 25, 2015 at 2:27 PM, Jean-Philippe Quéméner < jeanphilippe.queme...@gmail.com> wrote:

Disabling Query result cache at runtime

Hi, Is there a way to make solr not cache the results when we send the query? (mainly for query result cache). I need to still enable doc and filter caching. Let me know if this is possible, Thanks Nitin
