Search exclude nid
This module allows you to exclude specific nodes from your site's search results by entering their node IDs into a list. This prevents pages that display dynamic content, like node listings, from appearing as unwanted search results.
Sometimes it's necessary to exclude single nodes from the site search. An example use case would be, if you use the module "Insert view" to insert views into the body text of a node, which outputs a list of other nodes. A common problem is here, that the listing node is found as a second unwanted search result as it displays content of the listed item as its own (body) content. With this tiny module you can exclude these listing pages or other unwanted node pages from the search result by entering their node ids into an exclusion list.
This module does exactly this and nothing else.
