Canadian Trademarks Database Tutorial - Lesson 3: Refining Searches

If you’ve searched for a term and the Database has returned hundreds of records, you may want to refine your search so that you can find the “needle in the haystack”. In this section we will cover the following:

Using “search field” options

  1. You can search in specific fields by clicking the “Select a search field” drop-down menu.
  2. Select the desired search field. The default search field is “All”.

Searching with multiple criteria

To enhance a search, you can combine up to five additional search 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".

  1. Click “Add another search criteria”.
  2. Click the drop-down menu to select the desired operator.

    Note: Only criteria 2 to 5 have this option.

  3. If you wish, repeat the ‘Using “search field” options ’ steps.
  4. Enter the desired term(s) in the “search criteria” field for each criterion added.
  5. Once completed, click “Search” to view your results. You may choose to click “Clear” to restart.

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


Both search criteria will be included (e.g., "red AND apple" will locate records containing both these words)


At least one of the search criteria will be included. (e.g., "red OR apple" will locate all records containing at least one of these words)

But not

Excludes words or phrases (e.g., "red BUT NOT apple" will locate records that contain the word "red" but will exclude all records containing the word "apple")
