The bug fix for #12 .

[mpneuried]

I run into the same problem.
If you try to search for more than one word and the first word will not create a result you get an error like:

TypeError: invalid 'in' operand root
has(token="", root=1) in lunr.js (1185)

My Solution in lunr.js (1180) is

  var root = typeof(root) != "object" ? this.root : root,

This takes care of the var scope

The problem was actually a little further up than the token store, where the error was being thrown. I've pushed a new version with a fix. Thanks
