Here is what I have done so far
filter := bson.M{
"$or": bson.A{
bson.M{"title": bson.M{"$regex": "input"}},
bson.M{"author": bson.M{"$regex": "input"}},
bson.M{"content": bson.M{"$regex": "input"}},
},
}
p.postProposalCollection.Find(ctx, filter)
but it is case sensitive, is there anyway to lowercase the column title
, author
, content
then try to search with regex.
