Search functionality for custom playerData fields seems to be very unreliable.
Problems I can reproduce always:
) Searching for custom playerData field with two letter string. Example field "playerLanguage" has values like ES or FI.
Searching with playerLanguage = "FI" will return players with "ES", and players with no "playerLanguage" field set whatsoever.
) Searching for custom playerData with playerName = "Victor" will return players with default "PlayerName".
) Searching for custom playerData with playerRegion = "Spain" returns 0 hits even though we have 3,000 players with playerRegion Spain.
) Trying to use NOT boolean operator never works.
playerIcon = "beer" returns players correctly, but
playerIcon NOT "beer" returns 0 hits
