If you were only interested in the first element you could use a projection that repeats your $elemMatch
If you are interested in all elements that match, which your expect result shows, it is a little bit more complicated. You need a $filter projection such as:
{ "tags" : { "$filter" : {
"input" : "$tags" ,
"cond" : {
"$and" : [
{ "$eq" : [ "$$this.tag_name" , "Testnew" ] } ,
{ "$eq" : [ "$$this.status" , true ] }
]
}
} } }
