• Click on the Advanced Search link.

• To find relevant resources on the topic you are researching, look for the All Bibliographic Fields search box.

• Try typing the exact phrase "physical activity" (using double quotation marks) into the box.

• To broaden the search, type OR (in capital letters) and then add the keyword exercise. The search you've added to the box should now read "physical activity" OR exercise.

• To make the search more specific, use the "Choose one bibliographic field" drop-down menu to select the Title field. This means your listed results will contain only those items where one (or both) of these search terms appears in the title.

• Now click on the "+" icon to the right of the box to add another search term in a new box.

• Type the keyword obesity into the new search box and again select Title from the drop-down menu.

• Click on + to add another search box, type diabetes into this box, and then choose Title again.

• Before going any further, let's consider what you are searching for. You are asking for any research that contains either the phrase "physical activity" or the word exercise, and it must also contain the word obesity and the word diabetes, and you've limited your results to only those resources where your search terms appear in the title. This means that the results you see should be a lot more relevant than if you hadn't specified a field to search in.

• Now click on the blue Search button at the top. You should now see a list of about 50 results matching your search specifications.

• If you wish, you can still refine your search further using the options down the left - Free full text access, by Article type (e.g., Research articles and/or Review articles), or by Date. For now, let's just look at the results currently listed.
