1、fuzzy查询放在filter里
{
"size": 0,
"query": {
"bool": {
"filter": {
"fuzzy": {
"queryKeyword": {
"value": "男士拖鞋",
"fuzziness": 2,
"max_expansions": 50,
"transpositions": true
}
}
}
}
}
}
结果：
"hits" : {
"total" : 845274,
"max_score" : 0.0,
"hits" : [ ]
}
2、fuzzy查询放在must里
{
"size": 0,
"query": {
"bool": {
"must": {
"fuzzy": {
"queryKeyword": {
"value": "男士拖鞋",
"fuzziness": 2,
"max_expansions": 50,
"transpositions": true
}
}
}
}
}
}
结果：
"hits" : {
"total" : 47801,
"max_score" : 0.0,
"hits" : [ ]
}
这是什么原因呢？

把fuzzy放到must里匹配不到任何文档，
但是放到filter里是可以匹配到的
