Currently the only way of searching communities is by the name and description, which works quite well for the most part, but can obviously result in communities not being found when using alternative words or abbreviations. The community "Cannabis Furries" will not be found when searching many popular terms like weed, marijuana, pot, ganja, or any of the dozens of slang terms. It does show as a result for "420" - and that's only because the group description has a link that contains 420. The community "motor furs" doesn't come up when you search "cars". Adding searchable keywords to communities will greatly improve searchability without having to resort to adding keyword clutter into the description itself. It will also likely result in less duplicate communities being created.
