I have one search string which is gonna be my value and then I want to test every key in my collection if it has that value. Is there a way to make this work?

```
entry = db['names'].find({:firstname => "#{search}"}).to_a  
puts entry

```

let´s say if this worked I´d be happy: 

```
entry = db['names'].find({[:firstname, :lastname] => "#{search}"}).to_a 
puts entry

```
