Search Query Exclude

The Search Query Exclude module, allows site administrators to easily control the search results by providing a query to exclude nodes from the search result.

Use Cases:

1) Exclude nodes with php code using the default query provided

select nid from node_revisions where body like '%<?php%' group by nid

2) Exclude test nodes using the query

select nid from node_revisions where title like '%test%' OR body like '%test%' group by nid
