Slop问题纪录

简单的近似匹配

https://www.jianshu.com/p/485eff3d35bb

match_parse

匹配所有短语
匹配词语顺序保持一致
可以使用slop选择词语间隔和顺序

GET forum/article/_search
{"query": {"match_phrase": {"title": {"query": "java spark","slop" : 1}}}
}

slop的顺序纪录

curl -X GET "localhost:9200/my_index/my_type/_search?pretty" -H 'Content-Type: application/json' -d'
{"query": {"match_phrase": {"title": {"query": "quick fox","slop":  1}}}
}
'

slop的顺序控制时，slop的值不一定要大于短语的个数

栗子：

GET test/_search
{"query": {"match_phrase": {"field": {"query": "fox brown quick","slop": 2}}}
}

匹配结果：

{"took" : 0,"timed_out" : false,"_shards" : {"total" : 1,"successful" : 1,"skipped" : 0,"failed" : 0},"hits" : {"total" : {"value" : 2,"relation" : "eq"},"max_score" : 0.1377056,"hits" : [{"_index" : "test","_type" : "_doc","_id" : "OrJFAHAB2CC_oLWGufY0","_score" : 0.1377056,"_source" : {"field" : "fox quick brown"}},{"_index" : "test","_type" : "_doc","_id" : "VbIAAHAB2CC_oLWGB1eM","_score" : 0.10308687,"_source" : {"field" : "fox red blue brown quick"}}]}
}

猜测顺序：

fox brown quick

fox quick/brown
fox quick brown

/ 表示共用一个位置

栗子二

GET test/_search
{"query": {"match_phrase": {"field": {"query": "fox brown quick red","slop": 3}}}
}

结果

{"took" : 0,"timed_out" : false,"_shards" : {"total" : 1,"successful" : 1,"skipped" : 0,"failed" : 0},"hits" : {"total" : {"value" : 1,"relation" : "eq"},"max_score" : 0.2434652,"hits" : [{"_index" : "test","_type" : "_doc","_id" : "mrNbAHAB2CC_oLWGVyd0","_score" : 0.2434652,"_source" : {"field" : "fox red brown quick"}}]}
}

栗子三

GET test/_search
{"query": {"match_phrase": {"field": {"query": "fox brown quick red","slop": 4}}}
}

结果

{"took" : 0,"timed_out" : false,"_shards" : {"total" : 1,"successful" : 1,"skipped" : 0,"failed" : 0},"hits" : {"total" : {"value" : 3,"relation" : "eq"},"max_score" : 0.2434652,"hits" : [{"_index" : "test","_type" : "_doc","_id" : "mrNbAHAB2CC_oLWGVyd0","_score" : 0.2434652,"_source" : {"field" : "fox red brown quick"}},{"_index" : "test","_type" : "_doc","_id" : "3LNaAHAB2CC_oLWGoiVK","_score" : 0.2019119,"_source" : {"field" : "red fox brown quick"}},{"_index" : "test","_type" : "_doc","_id" : "VbIAAHAB2CC_oLWGB1eM","_score" : 0.17430875,"_source" : {"field" : "fox red blue brown quick"}}]}
}
