/* the filter operation codes that go in the key part of MatchMakingKeyValuePair_t should be one of these:
"map"
- Server passes the filter if the server is playing the specified map.
"gamedataand"
- Server passes the filter if the server's game data (ISteamGameServer::SetGameData) contains all of the
specified strings. The value field is a comma-delimited list of strings to match.
"gamedataor"
- Server passes the filter if the server's game data (ISteamGameServer::SetGameData) contains at least one of the
specified strings. The value field is a comma-delimited list of strings to match.
"gamedatanor"
- Server passes the filter if the server's game data (ISteamGameServer::SetGameData) does not contain any
of the specified strings. The value field is a comma-delimited list of strings to check.
"gametagsand"
- Server passes the filter if the server's game tags (ISteamGameServer::SetGameTags) contains all
of the specified strings. The value field is a comma-delimited list of strings to check.
"gametagsnor"
- Server passes the filter if the server's game tags (ISteamGameServer::SetGameTags) does not contain any
of the specified strings. The value field is a comma-delimited list of strings to check.
"and" (x1 && x2 && ... && xn)
"or" (x1 || x2 || ... || xn)
"nand" !(x1 && x2 && ... && xn)
"nor" !(x1 || x2 || ... || xn)
- Performs Boolean operation on the following filters. The operand to this filter specifies
the "size" of the Boolean inputs to the operation, in Key/value pairs. (The keyvalue
pairs must immediately follow, i.e. this is a prefix logical operator notation.)
In the simplest case where Boolean expressions are not nested, this is simply
the number of operands.
For example, to match servers on a particular map or with a particular tag, would would
use these filters.
( server.map == "cp_dustbowl" || server.gametags.contains("payload") )
"or", "2"
"map", "cp_dustbowl"
"gametagsand", "payload"
If logical inputs are nested, then the operand specifies the size of the entire
"length" of its operands, not the number of immediate children.
( server.map == "cp_dustbowl" || ( server.gametags.contains("payload") && !server.gametags.contains("payloadrace") ) )
"or", "4"
"map", "cp_dustbowl"
"and", "2"
"gametagsand", "payload"
"gametagsnor", "payloadrace"
Unary NOT can be achieved using either "nand" or "nor" with a single operand.
"addr"
- Server passes the filter if the server's query address matches the specified IP or IP:port.
"gameaddr"
- Server passes the filter if the server's game address matches the specified IP or IP:port.
The following filter operations ignore the "value" part of MatchMakingKeyValuePair_t
"dedicated"
- Server passes the filter if it passed true to SetDedicatedServer.
"secure"
- Server passes the filter if the server is VAC-enabled.
"notfull"
- Server passes the filter if the player count is less than the reported max player count.
"hasplayers"
- Server passes the filter if the player count is greater than zero.
"noplayers"
- Server passes the filter if it doesn't have any players.
"linux"
- Server passes the filter if it's a linux server
