Finally, I was able to create a native query it is as below,
db.order.aggregate([
{
$project: {
total_book_count: {
$sum: "$orderItem.qty"
},
total_purches_amount: {
"$sum": "$price"
},
monthly: {
$dateToString: {
format: "%Y-%m",
date: "$created_time"
}
}
}
},
{
$group: {
_id: "$monthly",
total_order_count: {
$count: {}
},
total_book_count: {
$sum: "$total_book_count"
},
total_purches_amount: {
$sum: "$total_purches_amount"
}
}
},
{
$sort: {
total_order_count: -1
}
}
])
My Java Class is like below, ultimately I want this output as an array.
#Getter
#Setter
public class StaticDto {
private String _id;
private Integer totalOrderCount;
private Integer totalBookCount;
private Integer totalPurchasedAmount;
}

Finally, I was able to create a aggregation query for my problem,
public ResponseEntity<List<StaticDto>> getStatistics() {
AggregationExpression totalQty = AccumulatorOperators.Sum.sumOf("orderItem.qty");
AggregationExpression totalPrice = AccumulatorOperators.Sum.sumOf("price");
Aggregation agg = Aggregation.newAggregation(
project()
.and(totalQty).as("total_book_count")
.and(totalPrice).as("total_purchase_amount")
.and("created_time").dateAsFormattedString("%Y-%m").as("month"),
group("month")
.count().as("totalOrderCount")
.sum("total_book_count").as("totalBookCount")
.sum("total_purchase_amount").as("totalPurchasedAmount"),
sort(Sort.Direction.DESC, "month")
);
AggregationResults<StaticDto> staticDtos =
mongoTemplate.aggregate(agg, "order", StaticDto.class);
return ResponseEntity.status(HttpStatus.OK).body(staticDtos.getMappedResults());
}

How to get Max and Min Value in MongoDB based on specific key?

I want to get the max and min value of the emp salary based on currency. every employee has a salary range based on currency also all the details in response should be unique. while I am using aggregation function min and max but it fetches the max and min value of salary amount but I need to get max and min based on currency field.
Sample Data:
[
{
"id": "1",
"emp_name": "emp1",
"data": [
{
"emp_country": "country1",
"emp_city": "city1",
"salary": [
{
"currency": "INR",
"amount": 5000
},
{
"currency": "INR",
"amount": 600
},
{
"currency": "MXN",
"amount": 400
}
]
},
{
"emp_country": "country1",
"emp_city": "city2",
"salary": [
{
"currency": "DOLLER",
"amount": 5000
},
{
"currency": "DOLLER",
"amount": 200
},
{
"currency": "MXN",
"amount": 400
}
]
}
]
},
{
"id": "2",
"emp_name": "emp2",
"data": [
{
"emp_country": "country2",
"emp_city": "city2",
"salary": [
{
"currency": "INR",
"amount": 5000
},
{
"currency": "MXN",
"amount": 200
},
{
"currency": "MXN",
"amount": 400
}
]
}
]
},
{
"id": "3",
"emp_name": "emp3",
"data": [
{
"emp_country": "country1",
"emp_city": "city1",
"salary": [
{
"currency": "MXN",
"amount": 400
}
]
}
]
},
{
"id": "4",
"emp_name": "emp4",
"data": [
{
"emp_country": "country1",
"emp_city": "city2",
"salary": [
{
"currency": "DOLLER",
"amount": 200
}
]
}
]
}
]
Expected Output:
city, country, the name should be unique and salary have max and min based on currency.
[
{
"emp_city": "city1",
"emp_country": "country1",
"emp_name": "emp1",
"emp_salary": [{
"currency": "INR",
"max": 5000,
"min": 600
},
{
"currency": "MXN",
"max": 400,
"min": 400
}]
},
{
"emp_city": "city2",
"emp_country": "country1",
"emp_name": "emp1",
"emp_salary":[ {
"currency": "DOLLER",
"max": 5000,
"min": 200
},
{
"currency": "MXN",
"max": 400,
"min": 400
}]
},
{
"emp_city": "city2",
"emp_country": "country2",
"emp_name": "emp2",
"emp_salary": [{
"currency": "INR",
"max": 5000,
"min": 5000
},
{
"currency": "MXN",
"max": 400,
"min": 200
}]
},
{
"emp_city": "city1",
"emp_country": "country1",
"emp_name": "emp3",
"emp_salary": [{
"currency": "MXN",
"max": 400,
"min": 400
}]
},
{
"emp_city": "city2",
"emp_country": "country1",
"emp_name": "emp4",
"emp_salary": [{
"currency": "DOLLER",
"max": 200,
"min": 200
}]
}
]

We can achieve the above result using an aggregation query.
$unwind - to deconstruct array of salary
$group - group by emp city, country, name, currency with min and max value of salary
$group - use another to push in emp_salary
$project - to show fields in your format
db.collection.aggregate([
{
"$unwind": {
"path": "$data"
}
},
{
"$unwind": {
"path": "$data.salary"
}
},
{
"$group": {
"_id": {
"emp_city": "$data.emp_city",
"emp_country": "$data.emp_country",
"emp_name": "$emp_name",
"currency": "$data.salary.currency",
},
"max": {
"$max": "$data.salary.amount"
},
"min": {
"$min": "$data.salary.amount"
}
}
},
{
"$group": {
"_id": {
"emp_city": "$_id.emp_city",
"emp_country": "$_id.emp_country",
"emp_name": "$_id.emp_name",
},
"emp_salary": {
"$push": {
"currency": "$_id.currency",
"min": "$min",
"max": "$max"
}
}
}
},
{
"$project": {
"_id": 0,
"emp_city": "$_id.emp_city",
"emp_country": "$_id.emp_country",
"emp_name": "$_id.emp_name",
"emp_salary": 1,
}
}
])

Search query:
String query="{\"query_string\":{\"query\":\""+searchTerm.toUpperCase()+"\",\"default_operator\":\"AND\",\"default_field\":\"primaryTerm\"}}";
Java Code for elastic Query:
SearchResponse searchResponse=null;
try {
String queryJson=json;
System.out.println("queryJson:"+queryJson);
//System.out.println(indexName);
SearchRequest searchRequest = new SearchRequest(indexName);
SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();
searchSourceBuilder.from(start)
.size(length)
.query(QueryBuilders.wrapperQuery(queryJson));
searchRequest.source(searchSourceBuilder);
searchResponse = elasticsearchRestTemplate.getClient().search(searchRequest, RequestOptions.DEFAULT);
For a Search Term = 'Ni' in an autosuggest drpDown I am getting zero hits for the field 'primaryTerm'
I also tried the termQuerybuilder instead of wrapper query:
SearchRequestBuilder searchRequestBuilder = client.prepareSearch("relmap");
SearchResponse searchResponse = searchRequestBuilder.
setQuery(QueryBuilders.boolQuery().must(QueryBuilders.termQuery("variants", "NATURAL REMEDIES PVT. LTD"))).setFrom(0).setSize(1000).setExplain(true).setTrackTotalHits(true).execute().actionGet();
SearchHits searchHits = searchResponse.getHits();
Interestinlgy I am getting the desired output with elastic url.
Elastic URI code:
http://localhost:9201/relmap/_search?q=NIC&df=primaryTerm&explain=true&default_operator=AND
Can anyone help let me know the fault /correct way to get the hits from the query

Obtaining a specific field in Elastic search using Kibana and Java

I am very new to ELK stack. I am trying to retrieve a specific field (like in MySQL think we have a table called "Users", trying to retrieve the "phoneNumber" column). I am in need of doing that using Java as well as using the queries typed in Kibana. (for example lets think we need to retrieve the field comments in the elastic search database) Thank you for the help. I am new to Stack Overflow. So if I have done something wrong in asking the question, please let me know, ill correct it. Following is the result obtained in kibana by typing,

where json build by this code:
String json = new Gson().toJson(price);
then i want to get single value, for example :
"plans":["postpaid-monthly-fix","postpaid-monthly-trial1","postpaid-monthly-trial7","prepaid-signature-item"]
i try with json.get("plans") but get syntax erro, any clue ?

Try the following:
