Elasticsearch 6.2.4
索引具有映射：
{
"watcher" : {
"aliases" : { },
"mappings" : {
"doc" : {
"properties" : {
"script" : {
"properties" : {
"body" : {
"type" : "text"
},
"description" : {
"type" : "text"
},
"title" : {
"type" : "text"
}
}
},
"super-user" : {
"properties" : {
"id" : {
"type" : "text",
"fields" : {
"keyword" : {
"type" : "keyword",
"ignore_above" : 256
}
}
},
"password" : {
"type" : "text"
},
"sha" : {
"type" : "text"
},
"username" : {
"type" : "text"
}
}
},
"watcher" : {
"properties" : {
"actions" : {
"type" : "object",
"enabled" : false
},
"condition" : {
"type" : "object",
"enabled" : false
}
}
}
}
}
}
}
}
有一个我想通过其_source.super-user.id值获取的文档：
{
"_index" : "watcher",
"_type" : "doc",
"_id" : "sAkqs2UBN8hNgeAd6VYT",
"_score" : 1.0,
"_source" : {
"super-user" : {
"id" : "rwkTs2UBN8hNgeAd902q",
"username" : "elastic",
"sha" : "7598562076f37c7376ccf5c6ad28e00c:0fa96e2c4c0136b12ae1708940c46a52"
}
}
}
如何获取此文档？
我尝试了嵌套查询：
const elasticsearch = require('elasticsearch');
const client = new elasticsearch.Client({
host: [
{
host: 'localhost',
protocol: 'http',
auth: 'elastic:password',
port: 9200
}
]
});
(async () => {
try {
const resp = await client.search({
index: 'watcher',
type: 'doc',
body: {
query: {
nested: {
path: 'super-user',
query: {
bool: {
must: [
{
match: {
'super-user.id': 'rwkTs2UBN8hNgeAd902q'
}
}
]
}
}
}
}
}
});
console.log(JSON.stringify(resp, null, 2));
} catch (err) {
console.error(err);
}
})();
但是我遇到了failed to create query错误：
{ Error: [query_shard_exception] failed to create query: {
"nested" : {
"query" : {
"bool" : {
"must" : [
{
"match" : {

"query" : "rwkTs2UBN8hNgeAd902q",
"operator" : "OR",
"prefix_length" : 0,
"max_expansions" : 50,
"fuzzy_transpositions" : true,
"lenient" : false,
"zero_terms_query" : "NONE",
"auto_generate_synonyms_phrase_query" : true,
"boost" : 1.0
}
}
}
],
"adjust_pure_negative" : true,
"boost" : 1.0
}
},
"path" : "super-user",
"ignore_unmapped" : false,
"score_mode" : "avg",
"boost" : 1.0
}
}, with { index_uuid="5O9HfcORTjiq5SZ0c1lkQA" & index="watcher" }

nested是一种特定的数据类型：https://www.elastic.co/guide/en/elasticsearch/reference/current/nested.html
在映射中，您没有指定它，因此请使用简单的点表示法选择没有嵌套查询的正确字段。
