Tips for searching

  • Start with the obvious.
    • Example: If you're looking for general information about Montreal, type montreal.
  • Use multiple search terms.
    • Example: If you're searching Montreal Canadiens, type montreal canadiens, rather than just montreal or canadiens by itself. 
  • Type your search in either uppercase or lowercase.
    • Example: Typing paula martin returns the same results as Paula Martin or PAULA MARTIN.
  • Use an asterisk (*) to replace one or many characters in a search term. 
    • Example: Type Wilfr*d, to get both Wilfrid and Wilfred
    • Example: Type patriot*, to get results with patriote, patriots, patriotism, patriotic, patriotique, patriotisme, etc.  

If you get too many results

  • Make your search more specific.
    • Example: Search for montreal molson centre rather than montreal arena.
  • Use quotation marks if you want results for an exact phrase.
    • Example: The search, "paula martin" does not find Paula Andrea Martin.

Formal titles appear prominently in or on the documents being described; are usually assigned to the document by the creator; and are considered authoritative.
