There was previously the worry of search explosions relating to the removal of this guard, I assume there is none anymore? Regardless nice gainer and nice idea! |

While this may have been written in hopes of guarding against search explosions, I don't think it deals with the core of the issue #5023 (comment). Of course I'd be happy to re-evaluate if it is found that this patch actually did bring back some search explosions. |
