The search terms or keywords you use to search are what determine the results you get. Here's a good exercise to help you generate keywords:
1. Express your topic in a topic sentence: “What is the effect of television violence on children?”
2. Generate keyword search terms by identifying the main ideas or concepts within that topic sentence: “What is the effect of television violence on children?” = Effect, Television, Violence, or Television violence and Children
3. Expand your search terms by brainstorming related terms or synonyms that describe your main ideas:
PITTCat+ is the gateway searching tool for all of the materials owned by the University Library system (ULS), including articles, books, e-books, journals, e-journals, e-audio and e-video, digital images, government documents, microfilm and movies.
Combining Search Terms - You can craft complex searches using Boolean operators AND, OR, and NOT. These operators must be written in ALL CAPS. The PITTCat+ searching default is the AND operator.
Phrase Searching - PITTCat+ allows for phrase searching with the use of “ “. For example, the search "pittsburgh renaissance" will find items with the phrase pittsburgh renaissance in them.
Wildcard and Trucation – You can use wildcard (*) and truncation (?) symbols to search PITTCat+.
