patch for Solr 1.3
this patch only DocSetBase implement Serializable
solr-memcache
=====================readme.txt=========================
MemcachedCache instead of solr queryresultCache (default LRUCache)
config in solrconfig.xml to use solr-memcache
add newSearcher and firstSearcher Listener, such as:
<listener event="newSearcher" class="solr.MemcachedCache" />
<listener event="firstSearcher" class="solr.MemcachedCache" />
use listener only for get index version, to create memcached key
indexVersion is static long field of MemcachedCache.java.
//originalKey is QueryResultKey
memcached key = keyPrefix+indexVersion+"-"+originalKey.hashCode()
<!--
MemcachedCache params:
memcachedHosts (required), "," split.
name (optional) no default.
expTime (optional) default 1800 s (= 30 minute)
defaultPort (optional) default 11211
keyPrefix (optional) default ""
-->

class="solr.MemcachedCache"
memcachedHosts="192.168.0.100,192.168.0.101:1234,192.168.0.103"
