Hi All,

I am using elastic search java api. We have indexed data as

GET eb\_portal\_index/part/\_search  
{  
"query": {  
"match": {  
"part\_no": "ME9143"  
}  
}  
}

We get result like

{  
"took": 16,  
"timed\_out": false,  
"\_shards": {  
"total": 5,  
"successful": 5,  
"failed": 0  
},  
"hits": {  
"total": 1,  
"max\_score": 11.686213,  
"hits": [  
{  
"\_index": "eb\_portal\_index",  
"\_type": "part",  
"\_id": "ME9143/0.0/null/null/null",  
"\_score": 11.686213,  
"\_source": {  
"part\_no": "ME9143",  
"min\_stock\_qty": 0,  
"latest\_price": 0,  
"latest\_leadtime": 0,  
"indexES": "part ME9143/00 IHC7\_Part",  
"revision": "00",  
"type": "IHC7\_Part",  
"object\_name": "ME9143",  
"object\_desc": "BB4026DU",  
"owning\_group": "Engineering",  
"uom\_tag": "each",  
"last\_release\_status": "Released",  
"date\_released": "2015-01-22T00:00:00.000+01:00",  
"last\_mod\_user": "Migrator (migrator)",  
"ihc7\_discipline": "Mechanical",  
"ihc7\_manufacturer": "",  
"ihc7\_manufacturerref": "",  
"bom\_qty": 0,  
"bom\_price": 0,  
"bom\_price\_total": 0  
}  
}  
]  
}  
}

Now I want to search all part in that index, which have object\_desc as empty or null , or object\_desc is not set for that part. Is it possible. How can i do in java

You can search using `exists` query inside a must\_not clause, see  
[https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-exists-query.html#query-dsl-exists-query](https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-exists-query.html#query-dsl-exists-query)

Exists Query in Java API : [https://www.elastic.co/guide/en/elasticsearch/client/java-api/current/java-term-level-queries.html#java-query-dsl-exists-query](https://www.elastic.co/guide/en/elasticsearch/client/java-api/current/java-term-level-queries.html#java-query-dsl-exists-query)  
And Bool Query : [https://www.elastic.co/guide/en/elasticsearch/client/java-api/current/java-compound-queries.html#java-query-dsl-bool-query](https://www.elastic.co/guide/en/elasticsearch/client/java-api/current/java-compound-queries.html#java-query-dsl-bool-query)
