Does hibernate search utilize second level cache

I have second level cache enabled in my app using:

Code:

            <property name="hibernate.cache.use_second_level_cache" value="true"/>
            <property name="hibernate.cache.provider_class" value="org.hibernate.cache.OSCacheProvider"/>
            <property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.JBossTransactionManagerLookup"/>

I can see the effect of caching when I load entities by PK. When I do search, however, I find search results always loaded from db, because after I search once, and modify db records by hand, the next search always turns up the latest information. I thought hibernate search uses Lucene to find the id, and then loads it from db. If that is the case, the loading part should be from cache. Does it not?

Thanks.

Like query.list() ignore the first/second level cache and query.iterate() benefit from the first/second level cache in HQL queries,
fullTextQuery.list() will ignore the caches and fullTextQuery.iterate() will use them.

Note that if you retrieve more than one entity type, the caches are always used.
