Research Process: Getting Started 

A. Search Tools

B. Search Strategies

There are three basic search strategies that can be used when trying to locate information:

• Keyword search: Quick way to retrieve a lot of results. Results will include every single record that contains your search term in any of the record fields searched. 
• Subject search: Looks for your search terms in the subject heading category. Subject headings are not determined through natural language but are chosen from predetermined lists of acceptable subject headings.
• Boolean logic: Frequently the basis behind an "advanced search" feature in a search tool. Once you have brainstormed your key concepts, you are ready to create a Boolean search. Boolean logic enables you to state relationships between the search terms using the following "operators":

1. And
   • Only records with BOTH search terms will be retrieved
   • The AND operator is the most commonly used operator
2. Or
   • Used to search synonymous terms or related concepts
   • This search will retrieve records where EITHER of the search terms is present, resulting in a larger number of hits
3. Not
   • Used to exclude a term or concept from your search
   • The NOT operator is the least-used operator

Different search tools (e.g., catalogs, databases, web) have different searching rules and features. You should always read directions and help screens before using a tool that is new to you.
