Use keywords and synonyms:
Start by taking keywords directly from your thesis statement.
Use synonyms and related concepts by thinking of other words that mean the same thing as the keywords in your question. Examples:
film or cinema or motion pictures
social media or Facebook or TikTok
gaming or video games or online gaming
Look at the subject terms in your search results and see if you can use any of those.
Use truncation:
You can broaden your search results by typing an asterisk symbol * at the end of the root of a word. When you do this, the computer will search for alternative endings for the word you have typed.
For example:
televis*
televise(d) televising television television broadcasting
