Query Post Counter
In case you were ever curious how many posts a specific query hits, then this is a useful tool for you. I made this tool a while ago for personal use and never posted it anywhere on the forum, so I decided to do that now.
It's a very simple tool, you put in a search query (like all of my projects, it uses the advanced search syntax for more specific searching) and the wizard that I hired for $20 will count all of the posts that the query hits and give you the count in a few seconds. More complex queries may take a little longer.
And if you want to see the source code, have at it. This is just the client side javascript, the actual counting part resides in my database mirror that handles the advanced search here
