They find a diverse, chaotic and decentralized tangle of information. Assistance is much more welcome after a frustrating voyage. Other problems with recall involve the amount of data returned. One of the best sites I found upon researching church arson came last on a list generated by my third try key words following 94 other places. The number of internet hosts tripled in the past year, certainly it's easy to contemplate not staying with a search through the third priority list.
Relevance has a great deal to do with the method of categorizing webpages.
They may be determined by the number of times the requested word is found on an entire webpage or by the location related to beginning or end of the page. Just as we learned which dictionaries in our collections include foreign terms within the body of the work and which contain a separate listing we will need to have a clear understanding of how the major search engines work. This will recall separate words if they are within ten words of each other. Lycos doesn't allow searches for numbers but many other search engines do. Several search engines expect words that need to be part of a phrase to be in quotes and some ask the user to put hyphens between them.
