Boolean Search Strings Cheat Sheet
Welcome to our comprehensive guide on Boolean search strings! Whether you're a seasoned pro or a beginner just dipping your toes into the world of Boolean searches, this cheat sheet will provide you with all the tools you need to craft effective search queries and find the information you're looking for.
But before we dive into the nitty-gritty of Boolean operators and search syntax, let's first define what exactly a Boolean search is and why it's so useful.
What is a Boolean Search?
A Boolean search is a type of search that uses special keywords, or "operators," to narrow down the results of a search query. These operators allow you to specify exactly what you're looking for and exclude any irrelevant results.
The name "Boolean" comes from the 19th-century mathematician George Boole, who developed a system of logic using binary values (true or false, on or off) that forms the basis of modern computer logic. In the context of search engines, Boolean operators are used to filter search results and find only the most relevant information.
Why Use Boolean Searches?
Boolean searches are incredibly useful for finding specific information on the internet. They allow you to be precise in your search queries and exclude any irrelevant results, saving you time and effort.
For example, let's say you're looking for information on the history of the bicycle. A simple search for "history of the bicycle" will likely yield a wide range of results, including news articles, websites, videos, and more. However, using Boolean operators, you can specify exactly what you're looking for and filter out any irrelevant results.
For example, you could use the operator "AND" to search for articles that contain both the words "history" and "bicycle." This would exclude any results that only mention one of these terms and only show you articles that discuss the history of the bicycle.
The Different Boolean Operators
There are several different Boolean operators that you can use to craft precise search queries. These include:
The AND operator is used to narrow down search results by requiring that multiple terms be present in the result. For example, a search for "history AND bicycle" will only return results that contain both of these terms.
The OR operator is used to expand search results by allowing for multiple terms to be present in the result. For example, a search for "history OR bicycle" will return results that contain either of these terms, or both.
The NOT operator is used to exclude certain terms from the search results. For example, a search for "history NOT bicycle" will return results that contain the term "history" but exclude any results that contain the term "bicycle."
Parentheses are used to group terms and operators together, allowing for more complex search queries. For example, a search for "(history AND bicycle) OR (cycling AND road race)" will return results that contain either the terms "history" and "bicycle," or the terms "cycling" and "road race."
Quotation marks are used to search for an exact phrase. For example, a search for "history of the bicycle" will only return results that contain this exact phrase, rather than results that contain the individual terms "history," "of," "the," and "bicycle."
Tips for Crafting Effective Boolean Searches
Now that you know the different Boolean operators and how to use them, here are a few tips for crafting effective search queries:
Use AND to narrow down your search results and find only the most relevant information.
Use OR to expand your search results and find more information on a given topic.
Use NOT to exclude certain terms from your search results and fine-tune your query.
Use parentheses to group terms and operators together and create more complex search queries.
Use quotation marks to search for an exact phrase.
Advanced Boolean Search Techniques
Once you've mastered the basics of Boolean searches, you can take your skills to the next level by using some advanced techniques. These include:
Wildcards are special characters that can be used to represent one or more unknown characters in a search query. For example, the wildcard "*" can be used to represent any number of characters, while the wildcard "?" can be used to represent a single unknown character.
For example, a search for "histor*" would return results that contain words like "history," "historical," and "historian," while a search for "histor?" would return results that contain words like "history" and "historx," where "x" is any single character.
Stemming is a technique that allows you to search for variations of a word by using a "stem." For example, the stem of the word "run" is "run," and the stem of the word "running" is "run." By searching for the stem of a word, you can find results that contain variations of that word.
For example, a search for "run" would return results that contain the word "run," as well as words like "running," "runs," and "ran."
Fuzzy searching allows you to search for words that are similar to, but not exactly the same as, a given term. This can be useful if you're not sure of the spelling of a word or if you want to find results that contain related terms.
For example, a fuzzy search for "bicylce" would return results that contain the word "bicycle," even though the spelling is slightly off.
Boolean searches are an incredibly powerful tool for finding specific information on the internet. By using the different Boolean operators and advanced techniques like wildcards, stemming, and fuzzy searching, you can craft precise search queries and find exactly what you're looking for.

How Hume Can Help
As a hiring team, it's important to have efficient and effective methods for finding and assessing job candidates. Hume is an interview intelligence platform that can help streamline the hiring process by recording, transcribing, and summarizing interviews.
One way Hume can assist with Boolean search strings is by providing accurate and searchable transcripts of interviews. With these transcripts, you can use Boolean operators to search for specific keywords and phrases within the interview, making it easier to find and review relevant sections of the conversation.
For example, let's say you're looking for candidates who have experience with a specific software program. By using the AND operator to search for the words "experience" and the name of the software program within the transcripts, you can quickly find and review the sections of the interview where candidates discuss their relevant experience.
In addition to providing searchable transcripts, Hume also offers a summary feature that highlights the most important points and key takeaways from an interview. This can be especially helpful when reviewing multiple candidates, as it allows you to quickly scan through the summary and focus on the most relevant information.
Overall, Hume's recording, transcription, and summary features can help streamline the hiring process and make it easier to find and assess job candidates using Boolean search strings.
