Hey all,

can somebody help me to translate this filter function into Erlang, pls?


	function(doc){
		if(doc.type =3D=3D=3D "tile"){
			return doc.key.length <=3D 8;
		}else{
			return true;
		}
	}


My first attempt was this, but I don't know how to do the "key.length =
<=3D
8" check and I'm not sure if this works at all:

	fun({Doc}) ->
		case {proplists:get_value(<<"type">>, Doc),
proplists:get_value(<<"key">>, Doc)} of
		{undefined, _} ->
			true;
		{_, undefined} ->
			true;
		{Type, Key} ->
			case {Type} of
			{<<"tile">>} ->
				true;
			_ ->
				false;
			end;
		_ ->
			true;
		end
	end.


Thank you,
Ingemar
