 The following query parameters can be used:
-
 - `type` (exact matching)
 - `developer` (exact matching)
 - `platform` (exact matching)
 - `tags` (exact matching, comma-separated array e.g. `/search?tags=Open Source,RPG`)
 - `title` ("contains" matching, e.g. `/search?title=brick` will return "**Brick**ster" and "**Brick**Breaker")
+- `random` (if true, the results will be in a random order)
 
 More than one query parameter can be specified. They will be concatenated in "AND" statements, i.e. `/search?type=homebrew&platform=GBC` will return every Homebrew developed with GBC features.
