Problem Description

Two queries that are basically the same (the only difference is that function_score is used in one of them) return different highlighting effects

Steps to Reproduce

create index: put my_index add data: POST my_index/_doc { "name":"互联互通技术" } DSL with function_score： GET my_index/_search { "query": { "function_score": { "query": { "match_phrase": { "name": { "query": "互联", "slop": 0, "zero_terms_query": "NONE", "boost": 1 } } } } }, "highlight": { "fields": { "name": { "pre_tags": [ "<span class=\"lawRed\" >" ], "post_tags": [ "</span>" ], "highlight_query": { "match_phrase": { "name": { "query": "互联", "slop": 0, "zero_terms_query": "NONE", "boost": 1 } } } } } } } DSL without function_score： GET my_index/_search { "query": { "match_phrase": { "name": { "query": "互联", "slop": 0, "zero_terms_query": "NONE", "boost": 1 } } }, "highlight": { "fields": { "name": { "pre_tags": [ "<span class=\"lawRed\" >" ], "post_tags": [ "</span>" ], "type":"plain" } } } } The highlighting results for the above two statements are different：

Sorry, the above DSL with function_score is wrong, actually it is: GET my_index/_search { "query": { "function_score": { "query": { "match_phrase": { "name": { "query": "互联", "slop": 0, "zero_terms_query": "NONE", "boost": 1 } } } } }, "highlight": { "fields": { "name": { "pre_tags": [ "<span class=\"lawRed\" >" ], "post_tags": [ "</span>" ] } } } }
