tools that have very high precision (number of relevant documents returned, say in the top tens of results). Each of the hundreds of connections can be in a number of different states: looking up DNS, connecting to host, sending request, and receiving response. System Features The Google search engine has two important features that help it produce high precision results. If that happens, and everyone starts running a distributed indexing system, searching would certainly improve drastically. Reduce manufacturing costs to little more than the cost of the required raw materials and energy. This is the technique the URLresolver uses to turn URLs into docIDs. Either of these cost saving advantages can make the return on investment for a small hydro site well worth the use of existing sites.

This will result in favorable scaling properties for centralized systems like Google. Make complex and molecularly intricate structures as easily and inexpensively as simple materials. Each crawler keeps roughly 300 connections open at once. In the current implementation we can keep the lexicon in memory on a machine with 256 MB of main memory. We expect to update the way that anchor hits are stored to allow for greater resolution in the position and docIDhash fields. Also, this makes development much more difficult in that a change to the ranking function requires a rebuild of the index. Work toward this goal has been done in Cho. But, because the cost of production of text is low compared to media like video, text is likely to remain very pervasive.

1.3.2 Academic Search Engine Research, aside from tremendous growth, the Web has also become increasingly commercial over time. Because of the immense variation in web pages and servers, it is virtually impossible to test a crawler without running it on large part of the Internet. In this case, the search engine can even return a page that never actually existed, but had hyperlinks pointing. But less blatant bias are likely to be tolerated by the market. Note that pages that have not been crawled can cause problems, how to cite image term paper since they are never checked for validity before being returned to the user.
