Thanks bro with the help! I try it this in template: search_forum_view (works):
<xf:if is="in_array({$searchForum.node_id}, [X,Y,Z])">
test and working only with node type forum search
</xf:if>
And this in PAGE_CONTAINER (works):
<xf:if is="in_array($containerKey, ['node-X','node-Y','node-Z'])">...
