Basic Strategy
Complex Searches
Ranges (years, names, report numbers)

Basic strategy:

  • Use quotation marks (" ") around "an exact phrase".
  • Use OR between terms to search for either one OR the other. for example,type "this phrase" OR "that phrase"
  • Minus signs (-) mean NOT. Use to EXCLUDE a -word or -"a phrase". for example,type "this phrase" -"that phrase"
  • Asterisks (*) are wildcards at the end of a partial word that can have multiple ending*.
    for example,type "public trans*" OR "rail transit" -bus
  • Colons (:) signal a range search.
    for example,type 1970:2000 in the YEARS field
  • Results are displayed as a list sorted by the most recent publication date (default). Use the dropdown options to re-sort the list.
    [screenshot of the SORT BY dropdown options]
  • When using more than one field, results must meet all criteria unless "OR" is selected in dropdown preceding the field.

Range of years, names, or numbers

You can search for items greater than or less than a certain value, or within a range. This is most commonly done when searching for publication years, but is also be useful for searching a range of report numbers or when unsure of the spelling of an author"s name.

Symbol Meaning Example
< less than (before) <2003 finds dates before 2003
> greater than (after) >2002 finds dates after 2001
: between 1997 : 1998 finds dates from Jan. 1, 1997 through Dec. 31, 1998 (inclusive)
In the author field, mach : mich finds all names between Mach* and the name Mich (inclusive)
