Include categories such as “college”, “high school”, “middle school” or “elementary school” as well as sizes “100-400 delegates″, “400-800 delegates”,  “around 1000 delegates”, “1500 and more delegates” in the box. You can also search by date and location. Write all of the above next to each other separated by spaces. You can also type in any other features that may appear in the descriptions of MUNs and, of course, conferences’ names, or anything of your interest. Examples:

November Guatemala high school 100-400 delegates

South Carolina March 2015

Note that some MUNs may not be found by categories concerning the size of the conference since not all of them have given such information.
