我有一个非常特殊的问题，就是查询一个布尔字段和一个嵌套到数组字段的字符串字段。索引映射如下：
indexes :string_field_1, type: 'string'
indexes :string_field_2, type: 'string'
indexes :boolean_field_1, type: 'boolean'
indexes :array_field_1 do
indexes :boolean_field_2, type: 'boolean'
indexes :string_field_3, type: 'string'
end
indexes :array_field_2 do
indexes :integer_field_1, type: 'integer'
end
indexes :array_field_3 do
indexes :integer_field_2, type: 'integer'
end
文档索引还有许多其他字段，这些字段不嵌套到数组字段，但必须包含在查询字段中。 我尝试过使用filter和bool查询的方法，如下所示：
"query":
{"bool":
{"must":
[
{"query_string":
{"query":"text which is being searched",
"fields":[
"string_field_1",
"string_field_2",
"array_field_1.string_field_3"
],
"fuzziness":"1","analyze_wildcard":true,"auto_generate_phrase_queries":false,"analyzer":"brazilian","default_operator":"AND"}
}
],
"filter":[
{"bool":
{"must":
[
{"bool":
{"should":
[
{"term":{"boolean_field_1":false}},
{"terms":{"array_field_2.integer_field_1":[x,z]}},
{"term":{"array_field_3.integer_field_2":y}}]}},
{"bool":
{"should":
[
{"term":{"array_field_1.boolean_field_2":true}},
{"terms":{"array_field_2.integer_field_1":[x,z]}},
{"term":{"array_field_3.integer_field_2":y}}]}},
]
}
}
]
}
}
]
}
}
此查询的问题在于它返回的文档在我看来并不需要返回。 在这种情况下，文件是下面的文字：
_source": {
"string_field_1": "text 1",
"string_field_2": "text 2",
"boolean_field_1": false,
"array_field_1": [
{
"boolean_field_2": true,
"string_field_3": "some text which is not being searched"
},
{
"boolean_field_2": true,
"string_field_3": "some text which is not being searched"
},
{
"boolean_field_2": false,
"string_field_3": "text which is being searched"
},
{
"boolean_field_2": true,
"string_field_3": "some text which is not being searched"
}
],
"array_field_2": [
{
"integer_field_1": A
}
],
"array_field_3": [
{
"integer_field_2": B
}
]
}
您可以注意到，array_field_1的第三项包含boolean_field_2：false以及正在搜索的文本。但是，根据我的filter：子句，只有array_field_1.boolean_field_2为true的文档必须被检索，除非发生array_field_2.integer_field_1：或array_field_3.integer_field_1，根据我的查询部分，这不是真的。 看起来有弹性并不考虑array_field_1 [2]是boolean_field_2为false的那个。 如何进行查询以便无法检索此文档？
谢谢你的进步， Guilherme的

另一种方法包括将array_field_1.string_field_3查询与boolean字段相关的bool查询放在一起：
"query":{
"bool":{
"should":
[
{
"query_string":
{
"query":"text which is being searched",
"fields":
[
"string_field_1",
"string_field_2"
],
"fuzziness":"1","analyze_wildcard":true,"auto_generate_phrase_queries":false,"analyzer":"brazilian","default_operator":"AND"
}
},
{
"bool":{
"must":
[
{
"query_string":
{
"query":"text which is being searched",
"fields":["array_field_1.string_field_3"],
"fuzziness":"1","analyze_wildcard":true,"auto_generate_phrase_queries":false,"analyzer":"brazilian","default_operator":"AND"
}
},
{
"bool":{
"should":
[
{"term":{"array_field_1.boolean_field_2":true}},
{"terms":{"array_field_2.integer_field_1":[x,z]}},
{"term":{"array_field_3.integer_field_2":y}}
]
}
}
]
}
}
],
"filter":
[
{
"bool":{
"should":
[
{"term":{"boolean_field_1":false}},
{"terms":{"array_field_2.integer_field_1":[x,z]}},
{"term":{"array_field_3.integer_field_2":y}}
]
}
}
]
}
}
遗憾的是，此查询还会检索文档。我真的不知道如何正确构建这个查询。
上面的查询组织为： （X）OR（A AND（B或C或D））

这是我的解决方案：
"query":{
"bool":{
"should":
[
{
"query_string":
{
"query":"text which is being searched",
"fields":
[
"string_field_1",
"string_field_2"
],
"fuzziness":"1","analyze_wildcard":true,"auto_generate_phrase_queries":false,"analyzer":"brazilian","default_operator":"AND"
}
},
{
bool: {
should:[
{
query:{
nested: {
path: 'array_field_1',
query: {
bool: {
must: [
{ match: { "array_field_1.string_field_3": "text which is being searched"} },
{term: {"array_field_1.boolean_field_2": true}}
]
}
}
}
}
},
{
bool:
{
must: [
{
query:{
nested: {
path: 'movimentos',
query: {
bool: {
must: [
{ match: { "array_field_1.string_field_3": "text which is being searched"} },
{term: {"array_field_1.boolean_field_2": false
]
}
}
}
}
},
{
query: {
bool: {
should: [
{"terms":{"array_field_2.integer_field_1":[x,z]}},
{"term":{"array_field_3.integer_field_2":y}}
]
}
}
}
]
}
}
]
}
}
]
}
}
