+
+## Searching
+You can search both for players and maps in a more *advanced* way. You can provide a case-insensitive regex or search term to get all matching entries. This is, however, paginated...
+
+- Search for player: `/api/players/search?q=name`
+- Search for map: `/api/maps/search?q=name`
+
+### Options (queries)
+These are queries you can use:
+- `q` : [String | RegExp] → This is the actual search term or regex.
+- `sort` : [String = field_name] → This chooses what field to sort by. Some example fields:
+    - `name` (player or map)
+    - `points` (player)
+    - `releaseDate` (map)
+- `order` : [String = asc | desc] → This chooses between ordering it by **asc**ending or **desc**ending order.
+- `page` : [Int = page_num] → This chooses what page to load in.
+- `byMapper` : [Boolean] (only for maps) → Searches by the mapper's name instead of by the map's name.
+
+### Examples
+- `/api/players/search?q=Yumiko&sort=points&order=desc` would search for players with `Yumiko` in their names, sort by their points in descending order (the one wiht the most points first).
+- `/api/players/search?q=burnyllama` would search for players with `burnyllama` in their names.
+- `/api/players/search?q=^[0-9]` would search for players with a name begining with a number.
