Sorry, I meant specifically in the arguments to xapian_index where
you're specifying a column in the data frame. My understanding is that
R supports both name indexing and numeric indexing, but it looked like
you were suggesting that (for instance) the ID column in the data
frame would only be specified by numeric index.
