How does the search result filtering work ?

As we transition to the new Hyland Community, some post links may be temporarily disrupted as we finalize redirects. We apologize for the inconvenience and are working to resolve this as quickly as possible. Details.

I find configuration below in alfresco:

    <!– All search results are filtered to exclude nodes that the current user can not        –>
    <!– read. Other methods restrict queries to those nodes the user can read                 –>

    <bean id="SearchService_security" class="org.alfresco.repo.security.permissions.impl.acegi.MethodSecurityInterceptor">
        <property name="authenticationManager"><ref bean="authenticationManager"/></property>
        <property name="accessDecisionManager"><ref local="accessDecisionManager"/></property>
        <property name="afterInvocationManager"><ref local="afterInvocationManager"/></property>
        <property name="objectDefinitionSource">
            <value>
                org.alfresco.service.cmr.search.SearchService.query=ACL_ALLOW,AFTER_ACL_NODE.sys:base.Read
                org.alfresco.service.cmr.search.SearchService.selectNodes=ACL_ALLOW,AFTER_ACL_NODE.sys:base.Read
                org.alfresco.service.cmr.search.SearchService.selectProperties=ACL_NODE.0.sys:base.Read
                org.alfresco.service.cmr.search.SearchService.contains=ACL_NODE.0.sys:base.Read
                org.alfresco.service.cmr.search.SearchService.like=ACL_NODE.0.sys:base.Read
                org.alfresco.service.cmr.search.SearchService.*=ACL_DENY
            </value>
        </property>
    </bean>
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

But after I navigate to MethodSecurityInterceptor.java, it seems that it only check if current user have the permission to call "query" method, but not filter all the nodes in search result.
Can someone tell me where does the filtering work ? In which class ?

Thanks in advance !

I'm not sure, this need to be confirm by alfresco team but i think that lucene search retrieve node without take security.
After for each node returned, Alfresco applies security : it checks static and dynamic rights.

If I'm right, lucene can found 200 nodes but when you display it to user you see only 10 nodes for instance.
