Subject [jira] Commented: (DIRSERVER-971) Provide specific filter nodes for True, False and Undefined, and handle them in the search engine
Date Sat, 14 Jul 2007 05:58:04 GMT

    [ https://issues.apache.org/jira/browse/DIRSERVER-971?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12512679

Ersin Er commented on DIRSERVER-971:
------------------------------------

We need these nodes to filter search filters before sending them to the core. Considering
DIRSERVER-955, suppose we have a filter like (!(x=y)(m=n)). If, according to the ACI information,
it's not permitted to FilterMatch x, we need to replace this node with UNDEFINED; if it's
not permitted to FilterMatch y, we need to replace this node with FALSE. So the core evaluator
module will directly know values of these nodes without querying them from backend.

> We need to be able to construct or modify search filters with special nodes for True,
False and Undefined. And the search engine should be able to handle these. This is especially
needed for DIRSERVER-955.
