Search Fields

The PLOS Search Fields are mostly self explanatory, though some names have special suffixes:

  • Fields ending with _date require a beginning date/time and an end date/time
  • publication_date:[2009-12-07T00:00:00Z TO 2013-02-20T23:59:59Z] searches the range Dec 7, 2009 to Feb 20, 2013 and, because of the requested timestamps (between the T andZ), includes content published during either of those days
