使用function_score进行分组处理,利用分组函数script_score进行自定义分值处理,
注意:使用script功能需要在配置中打开脚本功能:
script.inline: on
script.indexed: on
script.engine.groovy.inline.aggs: on
script.file: on
下图中的查询表示,查询termid为1238218的记录,或者displayname包含“宝宝”的记录;
termid为1238218的记录排序分人为设定为100,displayname等于“宝宝”的记录分值设定为99,其他按照displaynamelen排序;
{
"query": { "function_score": { "filter": { "bool": { "should": [ { "term": { "termid": "1238218" } }, { "match_phrase": { "displayname": "宝宝" } } ] } }, "functions": [ { "filter": { "term": { "termid": "1238218" } }, "weight": 100 }, { "filter": { "term": { "displayname": "宝宝" } }, "weight": 99 }, { "script_score": { "script": "_score + doc['level'].value" } } ], "score_mode": "first" } } }
