Hello,

Currently, I am using Elasticsearch version 5.3.2.  
I have multiple documents in the below format:  
{  
"id":"abc123"  
"question":"What is 1004 divided by 2?",  
"answer":" A. 52, B. 502, C. 520,D. 5002",  
"category": "math"  
}  
{  
"id":"asd456"  
"question":"Which is the nearest star to planet earth? ",  
"answer":"sun",  
"category": "general knowledge"  
}  
{  
"id":"nmb897"  
"question":"Which is the heavier metal of these two? Gold or Silver? ",  
"answer":"gold",  
"category": "science"  
}

I want to fetch documents with a category that falls under an array ["math","science"].

I have tried using terms query. But that didn't work.  
My query was like :  
{  
"query": {  
"bool": {  
"should": {  
"terms": { "category": ["math","science"]}  
}  
}  
}  
};

Help me with this.
