Following answer is based on my test in mongo shell -
I just created a sample in my collection. Here is how you can search for the documents with "Joe" -
db.sample3.find({"friends":"Joe"})
output is { "_id" : ObjectId("5339c9ff0bb9bc1b3a5bf7a4"), "name" : "Nicholas", "friends" : [ "Amy", "Joe", "Amanda" ] }
For the query db.sample3.find({"friends":"Amy"})
, output is -
{ "_id" : ObjectId("5339c9ff0bb9bc1b3a5bf7a4"), "name" : "Nicholas", "friends" : [ "Amy", "Joe", "Amanda" ] }
{ "_id" : ObjectId("5339ca120bb9bc1b3a5bf7a5"), "name" : "John", "friends" : [ "Amy", "Amanda", "Sam", "Steve" ] }
The query {"friends":"Joe"} works. So, you should be able to use the same in Mongokit. Here is the document I created -
db.sample3.find().pretty()
{
"_id" : ObjectId("5339c9ff0bb9bc1b3a5bf7a4"),
"name" : "Nicholas",
"friends" : [
"Amy",
"Joe",
"Amanda"
]
}
{
"_id" : ObjectId("5339ca120bb9bc1b3a5bf7a5"),
"name" : "John",
"friends" : [
"Amy",
"Amanda",
"Sam",
"Steve"
]
}
