No. The input data structure to xapian_index() will indeed be a data frame.
Even a stored CSV can be conveniently converted to a data frame. There are
few further modifications to xapian_index() function that are not indicated
in the example and I will provide a complete draft of the function after
reviewing those further.

Is there a specific way of implementing numeric indexing with Xapian? In R
numeric indexing can be used to extract content of a data frame (and other
R data structures). Since xapian_search() will return a data frame, its
elements can be conveniently extracted using various functions in R.

Best regards,
