Case Insensitive search with $in

Question

How to search a column in a collection in mongodb with $in which includes an array of elements for search and also caseInsensitive matching of thos

Answer 1

This works for me perfectly.

From code we can create custom query like this:

{
  "first_name":{
    "$in":[
      {"$regex":"^serina$","$options":"i"}, 
      {"$regex":"^andreW$","$options":"i"}
    ]
  }
}

This will transform to following in mongo after query:

db.mycollection.find({"first_name":{"$in":[/^serina$/i, /^andreW$/i]}})

Same for "$nin".
