member's list - show only members with x posts, allow search for all?

[boatdesign]

To prevent members list spam (members signing up only to get their profile on the members list) I changed the setting under options to show only members with more than 10 posts. However, a member noted today that this also made it so that you cannot search for members with less than 10 posts using the Search form on the member's list, which might be desirable to be able to do in some cases.

Would love to see a plugin/extension/mod or method to only include a member in the displayed members list if they have x number of posts, yet allow the search to find members with less posts if another member specifically searches for them.
