Bool query in array field - arrays

Question

I have a very particular issue concerning querying over a boolean field and a string field which are nested to an array field. The index mapping is as follow:
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
The document index also has many other fields which are not nested to the array field, but have to be included among the query fields.
I have tried an approach using filter and bool queries that is as follow:
"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}}]}},
]
}
}
]
}
}
]
}
}
The problem with this query is that it is returning a document which, in my opinion, doesn't have to be returned.
The document, in this case, is the bellow:
_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
}
]
}
As you can notice, the third item of array_field_1 contains boolean_field_2: false and also the text which is being searched. But, according to my filter: clause, only the documents which array_field_1.boolean_field_2 is true have to be retrieved, unless array_field_2.integer_field_1: or array_field_3.integer_field_1 occurs, which is not true, according to my query part.
It seems elastic is not considering that the array_field_1[2] is the one that the boolean_field_2 is false.
How can I make my query so that this document isn't retrieved?
Thanks is advance,
Guilherme

Answer 1

That was my solution:
"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}}
]
}
}
}
]
}
}
]
}
}
]
}
}

Answer 2

Another approach consists of putting the array_field_1.string_field_3 query together with the bool query related to the boolean field:
"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}}
]
}
}
]
}
}
This query also retrieves the document, unfortunately. I really do not know how to build this query properly.
The query above is organized as:
(X) OR (A AND (B OR C OR D))
