engineOptions gets stringified object, not index value

[snussik]

If you try to tokenize value with custom function in engineOptions section:

engineOptions: {
   profile: "speed",
   tokenize: function(str) {
      console.log(typeof(str), str) // <= here you'll get something like 'string' '{"name": "Itemname"}' not just Itemname
       return someTokenizeFunction(str)
   }
