You'll frequently run across sites that add lists of random words and phrases to their sites in order to attract people looking for something their site doesn't offer. Unfortunately, this is beacuse search engines don't have AI...they scan all known sites and ask the question ''does this site contain the words 'chromesn' entered...yes or no.''
Since the internet has become popular, everyone is creating their own web pages, most of which are 'junk.' If you type in the phrase ''the Ten Commandments,'' you're going to get a mix of results...everything from biblical quotes to sales pitches to sites offering things condemned by the Bible. It's tough wading through the junk to find what you want.
Thus, conducting a good search is now becoming an art. You have to give enough of a description to limit the amount of junk, but not limit it so much as to prevent the display of legitimate results. While you're mastering that ''technique,'' you'll want to check out Google's advanced search, which lets you type in words that must be included, words that can be included, words that you don't want included, and exact phrases that you'd like to have in the results. You can also filter out results that are old, in other languages, or originated from other countries. Then, if you use Yahoo search, you can also login and have certain domains (like www.advertising.com) automatically excluded from your search results. Once all of these ''filters'' have been applied, you'll reduce the number of hits from several million to several hundred, most of which will be exactly what you are looking for.
Hope this helps,
