What are the ways to accomplish exact title searches with z39.50? I'm looping through a list of MARC records trying to determine whether or not we own multiple copies of an item. After reading MARC field 245, subfield a I am creating the following z39.50 query: @attr 1=4 "foo bar" Unfortunately my local implementation seems to interpret this in a rather regular expression sort of way -- "* foo bar *". Does anybody out there know how to create a more exact query? I only want to find titles exactly equalling "foo bar". -- Eric Lease Morgan University of Notre Dame
