  • [1 = personal name 4 = title 7 = ISBN 8 = ISSN 1003 = Author Keyword 1035 = General Keyword]

RELATION

  • Controls the order of numerical expression, like date ranges
  • [1= less than 2 = less than or equal to 3 = equal 4 = greater or equal to 5 = greater than 6 = not equal]

POSITION

  • Specifies the location of term(s) within the fields for matching query, such as first or anywhere.
  • [1= first in field 3 = any position]

  • Specifies the structure of data in the query, a single word, a phrase, or a word list is searched
  • [1 = phrase 4 = year 6 = word list]
