I have an Unicode string like this: "chủ nợ đã kéo đến cửa hàng đồ  
gỗ".

As I follow the tutorial on the ElasticSearch website, I can search,  
for example:  
"hàng" and the result with highlight is beautiful.

The problem now is that I want to search for "hang" and still receive  
the same result with highlight in unicode.

Can anyone help me with this? If you do, please explain in clearl  
steps because I'm very new to search.

Thank you in advance!

Check the asciifolding filter in the analysis section:

.

You can build a custom analyzer that does ascii folding as well as one of  
its filters.
