我有这个索引:
{
"mappings": {
"records" : {
"properties" : {
"suggest" : {
"type" : "completion",
"contexts": [
{
"name": "year",
"type": "category",
"path": "year"
}
]
}
}
}
}
}
我写了一些记录:
POST http://localhost:9200/example/records
{
"suggest": {
"input": "foo123" ,
"contexts": {
"year": "1999"
}
}
}
POST http://localhost:9200/example/records
{
"suggest": {
"input": "some123" ,
"contexts": {
"year": "1999"
}
}
}
POST http://localhost:9200/example/records
{
"suggest": {
"input": "thing123" ,
"contexts": {
"year": "2000"
}
}
}
现在我会做这个查询(像sql一样):
SELECT * FROM example WHERE SUGGEST LIKE %123% AND YEAR=1999
如何在弹性搜索中进行操作?
我输入:
POST http://localhost:9200/example/records/_search?pretty
{
"query": {
"bool": {
"must": [
{ "wildcard" : { "suggest" : "*123*" } }
],
"filter":[
{ "term" : { "year" : "1999" } }
]
}
}
}
我已将此回复与空白结果一起返回:
{
"took": 1,
"timed_out": false,
"_shards": {
"total": 5,
"successful": 5,
"skipped": 0,
"failed": 0
},
"hits": {
"total": 0,
"max_score": null,
"hits": []
}
}
我希望能够归还这些记录:
我该怎么办?
答案 0 :(得分:0)
如果你关心得分,你需要使用必须bool query:
{
"query": {
"bool": {
"must": [
{ "wildcard" : { "name" : "*foo*" } },
{ "term" : { "year" : "1999" } }
]
}
}
}
或使用过滤器,如果您只想过滤值并可能缓存过滤器:
{
"query": {
"filter": {
"must": [
{ "wildcard" : { "name" : "*foo*" } },
{ "term" : { "year" : "1999" } }
]
}
}
}
