Tip #1: Select "TX All Text Fields" from drop down next to search boxes.
Tip #2: Use quotation marks when searching for a phrase or term with multiple words.
For example: When searching for higher education, enter "higher education" in the search box. This will help you retrieve relevant articles in a more efficient manner.
Tip #3: Use the word OR to make your search more expansive/inclusive.
For example: If you are looking for articles about medical/health care professions, you might want to search for:
careers AND (medicine OR nursing OR "physical therapy" OR "massage therapy").
This is one way to search using a number of alternative terms at the same time.
Tip #4: How are search results sorted? In some cases "Most Recent" is the default, in other "Relevance" may be the default. Take a look at both options and how they can affect the order of your results.
