Answer 1

i use "|" this character as a separator, so it is speacial for me. Key can be any character except of "|". it solve my problems thanks for answers. And it can be used with javascript, java and groovy. I tested it, worked.

var keyPrefix ="\\|[\u0000-\u007B\u007D-\uFFEF]*";
var keySuffix = "[\u0000-\u007B\u007D-\uFFEF]*\\|";
var searchkey = keyPrefix + key.toLowerCase() + keySuffix;
