Hello

I have document with nested documents:

> ```
> {
> "_id": 111
> "price": 1000
> "properties": [
> { "property_id": 22, "property_value": "gas"}
> { "property_id": 23, "property_value": "green"}
> ]
> }
> 
> ```

I have a request that gives me the expected score by the price (from 1 to 100).  
I need to add a +30 score if the nested document has a param\_id == 23 AND param\_value == "red". _However_, if the document doesn't have this nested document, then still return the document, just without these +30 score (can't just add filter that will delete the result without specific value)

I try:

> ```
> {
> "query": {
> "nested": {
> "path": "properties",
> "query": {
> "function_score": {
> "query": {
> "bool": { // search specific nested document
> "filter": [
> { "term": { "properties.property_id": 23 } },
> { "term": { "properties.property_value": "red" } }
> ]
> }
> },
> "script_score": {
> "script": {
> "source": "30" // if find nested document, then add 30 score
> }
> }
> }
> }
> }
> }
> },
> "sort": {
> "_score": {
> "order": "desc"
> }
> }
> }
> 
> ```

result: search\_phase\_execution\_exception

I try:

> ```
> {
> "query": {
> "bool": {
> "must": [
> [
> {
> "nested": {
> "path": "properties",
> "query": [
> {
> "function_score": {
> "functions": [
> {
> "weight": 30 // if find nested document, then add 30 score
> "filter": [ // search specific nested document
> {
> "term": {
> "properties.property_id": 23
> }
> },
> {
> "term": {
> "properties.property_value": "red"
> }
> }
> ]
> }
> ]
> }
> }
> ]
> }
> }
> ]
> ]
> }
> },
> "sort": {
> "_score": {
> "order": "desc"
> }
> }
> }
> 
> ```

result: [\_na] query malformed, must start with start\_object

I try:

> ```
> {
> "query": {
> "bool": {
> "must": [
> [
> {
> "nested": {
> "path": "properties",
> "query": [
> {
> "constant_score": {
> "filter": [ // search specific nested document
> {
> "term": {
> "properties.property_id": 23
> }
> },
> {
> "term": {
> "properties.property_value": "red"
> }
> }
> ],
> "boost": 30 // if find nested document, then add 30 score
> }
> }
> ]
> }
> }
> ]
> ]
> }
> },
> "sort": {
> "_score": {
> "order": "desc"
> }
> }
> }
> 
> ```

result: return document where has property\_id == 23 AND property\_value == "red", but add 1 score, and no dependence on boost
