Boolean opertors

A brief summary

Boolean operator is a tool to help us search library card catalog on internet faster and with more precision. The most common Boolean operators are AND, OR, and NOT. 

AND narrows or limits search by telling the database that all keywords used must be found in an article. AND search for two or more concepts by combining descriptive key words

Or broadens a search by telling the database that any of the words it connects are acceptable. It is helpful when we are searching for synonyms. I like to share one example from the internet here. For instance, if we type “death penalty” or “capital punishment” the results will include articles with either term.

NOT narrows our search by telling the database to exclude the information we do not want. This is useful when we are interested in a very specific task or information. It is also useful when we want to exclude a certain type of article.

Critical Analysis

I remembered the old famous saying “little knowledge is dangerous". I have no idea of any of the tools. I was actually taking a lot of time in getting information. In order to look for one kind of information on the net, I get thousands of results. I just keep on clicking one after another and at the end I land up getting so many stuff. Many of the stuff are usually unwanted and unnecessary. This wasted my time and resources. It took me so long to sort things out. Simple tool like Boolean operators makes the work easy and efficient. It saves time because we can look for things we want using this tool quite fast.

Future Commitment

The new knowledge on the use of the above tool will assist me henceforth. I may not waste my time and the resources which are precious. Using AND, OR, and NOT will guide my search on the web. I can also guide our colleagues because I know many do not have this idea. Thanks for the new idea!!!
