Planning out your search strategy -- especially search terms you want to use -- can make the research process easier. When picking out search terms (alternatively can be called "key words"), look at your research topic or research question along with any smaller questions or parts, and pick out the significant nouns or ideas. These will be your search terms. You should also think of all of the various ways those nouns or ideas could be expressed - if one variation doesn't work, try another.
Use a Keyword Brainstorming Worksheet to help you determine appropriate search terms. Here is an example:
You can also look for the controlled vocabulary that the tool you are searching uses (i.e. the catalog and library databases). Controlled vocabulary is a set of assigned terms to describe an item that are used consistently across the tool to make searching easier. These can be described as subjects, subject terms, or thesaurus terms.
The library's databases have different search interfaces, but they share basic search principles. Some of these principles are listed below.
It is good practice to look for the [Advanced Search] option in each database that you use. The advanced search page will usually make it very clear as to how you can control your search using Boolean search techniques, limiters, field searching, etc.
Boolean searching is the cornerstone to an effective search strategy. Boolean searching refers to searching using a combination of words and the three Boolean Operators: AND, OR, NOT. A best practice is to capitalize your Boolean Operators.
For example: "krispy kreme" AND marketing
For example: (adolescents OR teenagers)
For example: dolphins NOT football
To search for two or more words in the exact order in which they are entered you should enclose the phrase in quotation marks " ".
For example: "obsessive compulsive disorder"
Truncation allows you to search the root form of a word with all its different endings by adding a symbol to the end of a word. Truncation symbols vary by database (check the help screens or ask a Librarian), but are usually one of the below:
! (exclamation point)
? (question mark)
For example: advertis* will search for advertise, advertisement, advertising, advertises
Field Searching & Limiters
Each database has a variety of predefined fields or limiters that you can search within. Some examples of fields and limiters are:
