The header says it all. Can not search numbers. ie: 7-7. I know there is at least one with 7-7 in the subject line and a hundred more with 7-7 in the post.
Maybe there is a toggle in the search setup that allows for numbers? I may have to give up searching by MU's and search for the burried treasure this site contains in other ways.
It sure would be nice to be able to just type in your desired region for example 7-21 and then have any and all threads show up that are related to the region you wish to hunt!
