CONCLUSION
APPLICATIONS OF search engines
Among the different search engines only NorthenLight & Lycos are used .
The results of data processing of different searching experiments can be obtained by offer method.
The search engine Netscape has shown satisfactory results on testing on the topic Railway & Railway facilities.
By methods decision making of search engines, the research problem of operations can be reduced.
Look Smart is a double entendre, referring both to its selective, editorially compiled directory, and as a complement to users who are savvy enough to "look smart.".
These are the different applications of search engines.
CONCLUSION
The experimental testing has shown that with respect to specific topic, some search engines can be completely unsuitable due to distortion of results of searching.
The evaluation and rating of search engines has shown that within the framework of one particular topic, one - two search engines have competitive characteristics.
Natural coefficients of conditional relevance () for all search engines on all verifiable topics have appeared very low. The quantity of relevant documents in subject-matter area is from 0.4% to 10 %. This justifies the necessity to create retrieval systems specialized on topics. HcR
