Yes, the above statement is working good with filter only customer_name field.
I just notice that in my project code it uses combine 2 filter field using or_filters with name field and the search result is not consistent. Especially when I search with keyword contain number and sometime it return error by just change keyword.
Postman applies it automatically (optionally), but if it sees a string %nn it may conclude that you are handling URL Encoding yourself and therefore not apply it. Specifically, in your case, it sees %02 and interprets it as “STX” ASCII: start of text.
To debug such situations I typically copy Postman’s suggested curl command and paste it onto the command line. I then keep editing the curl command until I have figured out my error.
“500 Internal Server Error” is HTTPspeak for “Are you kidding me?”
