Searches for a term matching all documents is almost always the worst solution. In your case, it leads to first retrieving all documents, and checking if they match the filter one-by-one. A more efficient approach (and one I'm using successfully myself) is to run a BooleanQuery to match the two index fields PK and TYPE, and taking out tag:tag from the query altogether. This way, the indexing on the two terms will be used, so no CPU cycles at all will be used for documents matching neither PK nor TYPE.
