Report on the search results on final work

A report is presented on a search allows to estimate an informative situation on the topic of master's degree work. He is basic documentary confirmation of depth and plenitude of informative search, and also serves for fixing of current situation in the probed area.

A search was conducted on three languages by the followings most popular searching systems:

Google, Yahoo, MSN, Altavista is the international searching systems

Yandex, Rambler is the Russian searching systems

Meta is the Ukrainian searching system.

Results are erected in a table. He is executed twice with an interval a month and his results is erected in tables after 16.03.2010 and 16.04.2010. In tables the results of search are presented for to the indicated queries in each of the searching systems. Numerical values are the number of the documents found on demand.

A report on a search to 16.03.2010

Analysis of search results

When searching for information, the greatest number of documents provide the system Google, Yahoo, Yandex, Altavista, MSN. The least be efficient were of Rambler and Meta. When searching for a full match well-defined articulated theme the results search found nothing.

The most important queries for the keyword theme - “Mathematical design” and “Transients”. The average number of documents found at the request of “Mathematical design” is 4 000 000 in the search engine Yandex, 18 600 000 in the search engine MSN in the first time and 3 000 000 in the search engine Yandex, 22 300 000 in the search engine MSN in the second time. The average number of documents found at the request of “Transients” is 4 000 000 in the search engine Yandex, 5 540 000 in the search engine Altavista, 5 540 000 in the search engine Yahoo, in the first time and 2 000 000 in the search engine Yandex, 5 620 000 in the search engine Altavista, 5 640 000 in the search engine Yahoo in the second time. We can see, that in the search engine Google the results decreased on 1.34%, in the search engine Yandex the results decreased on 50%, in the search engine Rambler the results increased on 11.43%, in the search engine Yahoo the results increased on 1.81%, in the search engine Meta the results have not changed, in the search engine MSN the results increased on 17.49%.

Increasing the number of search results can be explained by an increase of interest in the subject of the request, which led to the expansion of the knowledge base search system. The sharp decrease in the number of search results is likely to indicate that was reindexing information database search engine.

Search engines gave good results on key phrases final work, but if you set the exact number of requests issued by the pages was very small, that indicating on the novelty of the study.
