An internet search engine searches the internet, or select pieces of the internet, based on important words, they keep an index of the words they find and where they find them, and they allow users to look for words or combinations of words found in that index. Earlier search engines only had a few hundred thousand pages and document and only received around one or two thousand inquiries each day compared to the hundreds of millions of pages and tens of millions of queries per day now a days.

A meta-search engine submits your query to several other search engines and returns a summary of the results back to you. Using a meta-search engine allows you a broader scope the results you get back are not always better than when you use a single search engine. A Boolean operator is a method of representing a relationship between sets using the operators AND, OR, and NOT. These Boolean operators are important because they connect the words you search according to rules for that index.
Internet search engines allow you to search the internet, or select pieces of the internet, based on the important words, keeps an index of words they find and where they found them, they also allow you to look for words/combinations of words. The internet allows students to conduct research, evaluate information (think critically about the information they find), and use that information to make a decision.
Students also run into problems like inaccurate information or believing everything they read, inability to distinguish different types of information, knowing how to really find information, and understanding citation and respecting copyright. Some questions students should ask themselves when researching on the internet are can you find the name of the author or creator? Are there any credentials/degree, title, etc.? Is there contact information somewhere on the page? Who is the author? What can you tell from the URL? What is the purpose of the web site? Is the site objective?
Is this information accurate? Is the information reliable and credible? Is the information current? When a student uses a meta-search engine it saves them time from using individual search engines. A meta-search engines create what is known as a virtual database from multiple single search engines and grab information from the most popular single search engines. Meta-search engines are different from single search engines because they show the results from single search engines in a different quantity and will list the results according to search engines that are used.
Search engines frequently have different ways they expect the requests to be submitted; some allow the word AND to be used while others require a + and some only require a space to combine the words. Using meta-search engines not only save a student time, but it also is a more effective way to search the web to get the information a student is trying to search; it is a tool that sends your query to several search engines to create a list from all its sources.
A Boolean operator defines the relationships between words or groups of words to ensure that a search containing different operators performs as you intend, us parentheses. The results may be different depending on how the Boolean operator AND is used with the Keyword Field. The Keyword Field automatically searches the Abstract, Descriptor, and Title fields’ altogether. If you are trying to search up stuff about jazz or blues music you would search jazz or blues to find articles that discuss either jazz or blues, OR always broadens your search.
When you search up jazz and blues the search finds articles that compare jazz and blues, AND always narrows a search than what OR does. If you search jazz not blues the search finds articles that are exclusively about jazz, NOT always excludes record with the specified term. With Boolean operators you should be extra careful with using NOT because it eliminates all catalog records that contain the term that comes after NOT, but can be useful when the search word has clusters in computing it also allows you to tighten up on your search by using NOT or AND NOT.
