Creating an effective search strategy is critical to undertaking a comprehensive search and identifying all relevant studies for your research question. After breaking your research question into discrete concepts, expanding those concepts to identify additional keywords and considering the search techniques you should use (such as truncation, wildcards, phrase or

Boolean Operators Boolean Search Operators are useful in joining together search keywords to narrow down your results and factor in potential synonymous terms. Learn more about the three operators and how they can be used in the video below. Boolean operators, or Boolean logic comes to us from mathematician George Boole. Boolean operators used by keyword databases for research are: AND OR NOT When used in a single search bar, these operators are to be placed between keywords to Creating a search strategy Bibliographic databases are highly structured with sophisticated indexing and so require a more strategic search approach compared to a simple Web search. To design your search strategy you need to: Identify key concepts Decide on which keywords to use Find relevant Subject Headings We advise that you plan out your search

Creating a Search Strategy

A Search Strategy is a method of preparing to do research. Having a search strategy will help you find better sources faster. These strategies will work in any environment (Google or databases), but they work best in databases. Use the following steps to create a good search strategy. Determine the keywords of your topic or research question (databases don’t

Introduction to Boolean Operators B oolean Operators are words that connect keywords (search terms) together to broaden or narrow the results retrieved. In library research they are often used with the library’s research databases or the library catalog. The three Boolean operators are AND, OR, and NOT. Searches that use Boolean operators to combine keywords will produce more effective search results than sentences. AND, OR and NOT are the most popular Boolean operators.

Scoping Searches: this is where you will experiment with your search terms and with different databases. It’s a chance for you to scope out the literature, get an idea of what is there and what language you will need to use to Boolean searching allows the user to combine or limit words and phrases in an online search in order to retrieve relevant results. Using the Boolean terms: AND, OR, NOT, the searcher is able to define relationships among concepts.

Boolean Operators connect your keywords to create a logical search that the database can understand. This may involve forcing the databases to look for multiple terms/concepts at once, which will make your search more precise. This creates a more power search with a higher percentage of relevant results. This page will show you how to use Remember if you need assistance with finding articles, or setting up a search strategy, please feel free to contact me.

Search Strings Are you finding too much or not enough information? Try using boolean operators and truncation symbols, or use alternative, narrower, or broader keywords to vary your results. To retrieve the most relevant search results, you A Boolean Operator is a simple word that communicates search strategies to a computer. This might seem like something technical, but it’s actually used very commonly. In fact, if you’ve ever Googled something (which, let’s be honest, you have), you’ve technically used Boolean operators (they just added them automatically for you).

Guidance on the steps involved in doing a systematic review, and ways in which the Library can help. Tips on developing a comprehensive search strategy for a systematic review including search operators, truncation and phrase searching.

Boolean Logic Boolean operators are terms you can use to narrow or broaden your search in a database or Google Scholar. The three basic operators are: AND, OR, and NOT. Why Use Them? To focus a search when you are using multiple terms. To include synonyms for your search terms in order to find all variations. To exclude terms not relevant to your search.

Why use Boolean operators? Using Boolean operators is the most efficient way to focus your search when a topic contains multiple search terms. Complete sentences are not good searches. When searching a database, Boolean operators make it easier for the database to process the information in the search and give you exactly what you Boolean operators form the basis of mathematical sets and database logic. They tell the database how you want your keywords to be connected in the search. You can use them to narrow or broaden your set of results. Choose which to use based on what is logical to include or exclude for your specific need. Why use Boolean operators? To focus a search, particularly

When searching one of Grand Canyon University Library’s many fabulous databases, did you ever notice the small boxes labeled “AND” and wonder, “What am I supposed to do with those?” Those are Boolean Operators and they can be a very effective tool when doing your online research. By using Boolean Operators, you can change the way the database Boolean operators serve as the underpinning of navigating and retrieving the desired results from a database or search engine. Understanding how these operators function and their relationship to your search terms will serve you well in your research. Step 7. Boolean Operators Once all free-text terms and controlled vocabulary terms have been identified, you can start the proper searching process. It is recommended to search for each identified search term individually, then use the correct Boolean operators to combine the terms. This will help prevent any human errors.

You can use the search operators AND, OR and NOT to combine search terms. These are the most commonly known and used boolean Search techniques In addition to Boolean operators, you can also use symbols in your search to make it more effective. We have listed the most common search techniques in the table below. Different databases may use different symbols – if you aren’t sure, look for the ‚Help‘ option in the database you are using. A Boolean operator refers to the logical use of algebraic terms involving two or more values. Boolean operators are used in computer database searching to connect research concepts.

Step 3: Developing a Search Strategy

The databases will often not understand your search if you enter it as a normal sentence, such as your full research or PICO question. Instead, you want to use the search terms that you brainstormed to create a Search Strategy. By using Boolean Operators and Parentheses, you can tell the databases precisely how you want your search terms to be searched.

The Boolean operators AND, OR, and NOT are often used to combine keywords when searching research databases. Use of these operators can make your search more focused, thus yielding more precise search results. Boolean operators tell a database how to combine your search words and what words you do or do not want in your results. Instead of finding thousands of irrelevant results, you can create a search which finds a much smaller number of useful results. Use BOOLEAN OPERATORS to relate the terms in specific ways that will affect the results of a search. Boolean operators are terms that create

Search operators (also called Boolean operators) allow you to include multiple words and concepts in your searches. This means you can search for all of your terms at once rather than carrying out multiple searches for each concept. There are three main operators: OR – for combining alternative words for your concepts and widening your results e.g. „social justice“ Boolean operators tell a database how to combine your search words and what words you do or do not want in your results. Instead of finding thousands of irrelevant results, you can create a search which finds a much smaller number of useful results.

How do I translate a search strategy for different databases? To make sure that your search strategy is consistent across all the databases you are using, you will need to understand any differences that exist to how they each apply Boolean operators, adjacency (or proximity operators) and search symbols such as truncation, wildcard and phrase searching. This tool is designed to help you create a search string using Boolean search operators. Add your key concepts and synonyms then click the button. The resulting search string can be copied and pasted into a database search box or UMBrella.

LibGuides: Research Tutorial: Strategic Searching

Searching literature systematically is useful for all types of literature reviews! However, if you are writing a systematic literature review the search needs to be particularly well planned and structured to ensure it is: comprehensive transparent replicable These help ensure bias is eliminated and the review is methodologically sound. To achieve the above goals, you Boolean operators use capitalised words (such as AND, OR, NOT) to produce more relevant results, when searching in a database. Using AND between words finds results containing those words.
