query cache result
hi,
i understand that queryResultCache tag in solrconfig is the one which
determines the cache size of SOLR in jvm.
<queryResultCache class="*solr.LRUCache*"
size="*${queryResultCacheSize:0}*"initialSize
="*${queryResultCacheInitialSize:0}*" autowarmCount="*
${queryResultCacheRows:0}*" />
out of the different attributes what is size? Is it the amount of memory
reserved in bytes ? or number of doc ids cached ? or is it the number of
queries it will cache?
similarly wat is initial size and autowarm depicted in?
can some please reply ...

thanks tomas ..
can we set querywindowsize of particular query through url ?
say, i want only a particular set of query's result to be cached and not
other queries . is it possible to control this query cache results and
window size for each query separately ?

If you set the size of this cache to 50, that means that Solr will keep in
memory the last 50 queries with their list of resulting document IDs.
The number of IDs per query can be configured with the parameter
queryResultWindowSize

wiki says *"size
The maximum number of entries in the cache."
andqueryResultCache
This cache stores ordered sets of document IDs — the top N results of a
query ordered by some criteria.
*
doesn't it mean number of document ids rather than number of queries ?

Hi Jame, the size for the queryResultCache is the number of queries that
will fit into this cache. AutowarmCount is the number of queries that are
going to be copyed from the old cache to the new cache when a commit occurrs
(actually, the queries are going to be executed again agains the new
IndexSearcher, as the results for them may have changed on the new Index).
initial size is the initial size of the array, it will start to grow from
that size up to "size". You may want to see this page of the wiki:

Tomás
