Searching

For most searches, there is no need to enter any special operators or commands. The search engine will try to find the most relevant items with the words you use.

Search Tips

Phrase Searches

To search for an exact phrase, enclose the phrase in quotation marks.

E.g., If you type Health Canada, the search engine will retrieve all records that mention health or Canada. If you type “Health Canada” in quotations, the search engine will only retrieve records that contain the exact phrase entered.

Lower- or Upper-Case Letters

The search engine is not case-sensitive. For example, a search on nice will also retrieve results on the National Institute for Health and Care Excellence (i.e., NICE).

Spelling Corrections

The search engine will automatically search variations on common words, but may also suggest alternate words or corrections to typos and spelling errors, especially if no results were found.

Basic Search

In the main search box, you can enter words or phrases. It is not necessary to enter any specific operators or commands because the search engine will try to find the most relevant results with the words you use.

Search Operators for Basic Search

Boolean Operators

In the main search box, you can combine search terms with the AND, OR, and NOT Boolean operators. The Boolean operators must be in ALL CAPS.

E.g., To find records related to FDA medical devices, you can combine the key terms using Boolean Operators: FDA AND device.

Grouping Terms

You can use parentheses to group terms and phrases. This can be very useful if you want to control the Boolean logic for a query.

E.g., To search for records that contain safety or advisory, but not >device, type: (safety OR advisory) NOT device.

Using Wildcards and Truncation

Wildcards are used to search for a root word’s alternate spellings and variations. Wildcards take the place of 1 or more characters in a search term.

A question mark (?) is used for single character searching (anywhere in the word). It is most useful to search for variant spellings of a word.

E.g., p?ediatric will return results for paediatric or pediatric.

An asterisk (*) is used for multiple character searching. It is used at the end of a root word (referred to as truncation) to search for variable endings to a root word.

E.g., gene* will retrieve gene, genes, genetics, and generation, generalized, generalization.

Advanced Search

The Advanced Search allows you to perform more specific searches by selecting one of the following search fields: Title, Category, Organization, Country, or Language.

To access the Advanced Search form, select the Advanced Search tab.

Use the Select a Field dropdown menu to select a field that you would like to search, then type in your search terms. You can search up to 3 fields at once to help narrow down your search results. You can choose Contains to search for the terms you entered or Does Not Contain to exclude the terms you entered.
