Find a row or a list of rows and create a cursor to iterate over the
result.

Params:
  • filter – the table filter (which possibly knows about additional
           conditions)
  • first – the lower bound
  • last – the upper bound
  • intersection – the geometry which values should intersect with, or
           null for anything
Returns:the cursor to iterate over the results
