Lesson 3: Refining Searches
If you've searched for a term and the Database has returned hundreds of results, you will want to refine your search so that you can find the "needle in the haystack." In this section we will cover the following:

See the "Searchable Fields" section of the Database's Help file for detailed explanations of each search field option.
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 Trademarks Database. You will notice 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."
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 documents containing both these words)
- 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")
