Lesson 3: Refining Searches

Searching with Multiple Criteria using Advanced Search

If you need to conduct a search that requires you to combine multiple search criteria, you need to use the Advanced Search feature of the Canadian Trade-marks Database.  You will noticed that there are five possible search boxes on the Advanced search page. To refine a search, you can combine up to five different criteria when performing a single search.

An "operator" is used to tell the search engine how to combine the different criteria. There are three types of operators: "AND,” “OR,” and “BUT NOT."

Searches 2 to 5 have an option to select an "operator."

Operators for different criteria

When entering multiple search criteria, select an operator based on the result you need:

  • AND
    Both search criteria will be included (e.g., "red AND apple" will locate documents containing both these words)
  • OR
    At least one of the search criteria will be included. (e.g., "red OR apple" will locate all documents containing at least one of these words)
  • BUT NOT
    Excludes words or phrases (e.g., "red BUT NOT apple" will locate documents that contain the word "red" but will exclude all documents containing the word "apple")
