I first keyed in the terms “vegetarian AND thanksgiving.” Bing turned up 4,780,000 results for this request. When I searched “vegetarian OR thanksgiving,” Bing found 28,300,000 results. After searching “vegetarian NOT thanksgiving” 20,400,000 results turned up, and “thanksgiving NOT vegetarian” turned up 22,300,000 results. Using this search tool, AND narrowed the search while OR broadened it. NOT isolated the search so that it only turned up documents containing one term but not the other.
In order to see how Bing filters keywords (whether it includes stop words or not) I typed in the question “Where can I find thanksgiving recipes that are vegetarian friendly?” Bing turned up 522,000 results, the first five of which were relevant to my query. The seventh result, however, paid attention to the term “friendly” and gave me information on “diabetic-friendly thanksgiving recipes.”
Doing a manual search using “thanksgiving+recipes+vegetarian,” Bing came up with 24,800,000 results, four out of the first ten were relevant to my query. The other six simply contained “thanksgiving,” “recipes,” and “vegetarian” somewhere in their documents.
In addition to the perspective of a user on an information retrieval system, there are also the perspectives of the source and the system itself. The most efficient index structure is the inverted file, which I arranged for two documents. An image of my arrangement of the documents “museum and Durer Rembrandt Turner of Constable gallery” and “ancient which gallery Egyptian artifacts Assyrian museum” is shown below.
