I am using multi match in several fields and when I try to search with keyword, ES applies higher score to which has more matching words.
IE, If I try to search with
valentine and Document A has
valentine XXX valentine and Document B has
valentine XXXXXXXX, Document A has higher score than B.
I want to apply same score to them if they have valentine regardless of counts.
This must be done in multi_search because I have to search it in several fields.
About analyzer, I am using customized one and it is below
filter : "owercase, asciifolding"
tokenizer : "letter"
Hope to hear suggestions from elastic experts
