Hey guys, I'm just wondering why the first example works, and the second doesn't? What am I missing there? [https://gist.github.com/matcouto/a8778cb21e3d8da73e79da3b8914f23a](https://gist.github.com/matcouto/a8778cb21e3d8da73e79da3b8914f23a)  
######### This works ##########  
{  
"query": {  
"bool": {  
"must": [  
{  
"constant\_score": {  
"filter": {  
"missing": {  
"field": "given\_name"  
}  
}  
}  
},  
{  
"wildcard": {  
"family\_name": "_hen_"  
}  
}  
]  
}  
}  
}

######### This doesn't work ##########  
"query": {  
"bool": {  
"must": [  
{  
"constant\_score": {  
"filter": {  
"missing": {  
"field": "given\_name"  
}  
}  
}  
},  
{  
"terms": {  
"status": [  
"Active"  
]  
}  
}  
]  
}  
}

Is this a good approach for combining queries and 'missing' filter? I just want to be able to search by null values while also adding new constraints

Thanks in advance
