There aren't many filters on the search page but if you're searching from the rankings page then please check if you have filters set that would exclude the player you are looking for. Click on 'Reset filters' to make sure the filters are off and try again. If you still can't find a player then they are probably not on the system yet.
If you are searching from the player compare page they may be additional filters if the comparison is restricted to an event. We have just started doing this with the PSA events.
If you are searching from the player invite page then you will only see unregistered players listed. If the player you're looking for isn't showing then they could well already be members.
There are a very large number of players on the system, nearly all added automatically as their results were received from a source league or tournament system. However, not all league and tournament systems feed results to SquashLevels so it's possible that some players have not been added.
If you would like a player and their results to be added to the system, the best bet is to ask the league or tournament organiser to ask their system provider to get in touch with us and we'll help them set up an automated feed quickly and easily. Feel free to copy us at firstname.lastname@example.org so we can follow up. Don't be left out of the fun!
If you have played a competitive match against the player, and they agree to have that match recorded, then you can record the result on the system yourself and add them that way.
