Here is my JSON file:

    "name": "chetan",
    "age": 23,
    "hobby": ["cricket", "football"]
}, {
    "name": "raj",
    "age": 24,
    "hobby": ["cricket", "golf"]

Here is the golang code I tried but didn't work as expected.

id:= "ket"
err = c.Find(bson.M{"$hobby": bson.M{"$search": id,},}).All(&result)

It gives error:

$hobby exit status 1

    From $search I'm assuming you're trying to use a text index/search, but in your case that wouldn't work. Text index doesn't support partials. You can still use regex to find those documents, but performance wise it wouldn't be a wise choice probably, unless you can utilize the index - which in your case wouldn't happen.

    Still, you could achieve what you want with:

    id := "ket"
    regex := bson.M{"$regex": bson.RegEx{Pattern: id}}
    err = c.Find(bson.M{"hobby": regex}).All(&result)
