I hear I can rename the value in index pattern, but I cannot find this. I can only change the type. eg. from number to string. Now I need to change value itself.  
eg. product\_shoes --\> shoes  
..and so on

Hello,  
You can use the field alias datatype in the mapping:

Thanks. I actually found what I was looking for and that is Static lookup as field type

Ah great, you wanted to change the values of a field inside a document, not the name of a field. Static lookup is indeed the answer. 🙂
