e.g.
Documents with two fields: prefix and name
1. name is analyzed using whitespace tokenizer and n-gram
filter(min=1,max=20)
2. I also extract the first character from name and indexed it without
analyzer
After setting up the index, i use TransportClient to do the search
request on useing QueryStringQueryBuilder on fields: name(no prefix)
and highlight fields are only: name
suppose i have a document:{"name":"null", "prefix":"n"}
when i search with: n, the result is ok and aslo correctly highlighted
however when I search with: prefix:n, it still highlight "n" which is
not what i want.
Does anyone here know why and how to fix it?
