Exclude Node
Rob Whitelock
Performs a similar function to the Logic node, but excludes any posts matched by its enclosed nodes. Positioning an Exclude node before a Logic node should prevent the Logic node from scanning the excluded posts. Positioning an Exclude note after the Logic node should exclude any posts matched by the Logic node. Placing the most restrictive pattern first in the chain will result in increased efficiency. (for example. excluding all posts that do not match a particular language, tag or moderation criteria before passing them to the next Logic node.)
