I know this question might seem a little odd, but it came up today in my discussion with someone on how search results should be returned. When you go to google and you type in something like: black cat (No quotes, just as seen above) How does it return the results. Does it: 1) Give all results that match black AND cat only. 2) Give results that match or black OR cat, but list black AND cat first, then move onto the other results. This is hard to test since it will only let you look at the first 1,000 results, and it can be difficult to find a combination of words that return that few results. Thank you in advance.
Not sure what you mean. First page seems to be all black AND caterpillar, which could fall into either group.
Google consider so many things when returning results. I saw some where that google consider about 200 factors in returning results.
Hi friend, Here is little info about how search work : First a crawler is been developed to index whole web. The information is stored in the database in systemic manner. A Search engine is been programmed and Algorithm is been implemented. Algorithm is been tested and implemented. Page rank technology is been used to rank page rank. PGR system is complex and is kept secret by their makers. A webpage is given a PGR and displayed in the search results acc 2 it. The whole system is dynamic Google has programmers to work around 24 hours for fixing up things and implementation of some thing new in it. ------------------ If you have make your own serach engine dont worry use Yahoo Boss. For addtional information about refer this link. Good Luck!
Their algo is not known and it looks for hundreds of things. However, Google returns results based on relevance.
