Search result
     For writing of master's degree work it is necessary to study the great number of different reasons, documents, articles. Most materials are in free access in the Internet. For an information retrieval in the World spider web utillize searching sites.
     The complex of the programs, providing functionality of the searching system, is named by a searching rendering-engine or searching machine. Basic performance searching machine measures are relevance, plenitude of base, account of morphology of language. Indexation of information is carried out the special searching robots. Improvement of work of the searching systems - it one of priority tasks of the today's Internet.
     For an information retrieval I utillized the followings searching systems:
1. google.com.ua
2. yandex.ru
3. yahoo.com
4. rambler.ru
5. msn.com
6. meta.ua
7. aport.ru
8. altavista.com

A red color is mark those results which for last period was increased. Dark blue a color is mark those results which diminished for last period.
     We will analyse the got results. We will mark first, that searching system Aport differs the unauthenticity of results of search. Pre study of results of search from this searching system a lot of garbage was noticed - documents, not proper a query. At a search in Russian language it is possible to mark leading of Google as compared to Yandex (other searching systems are shown by worst results), although exactly Yandex is positioned as the best searching system of Runet. Leading of Google in a search in English language does not cause doubts. There is Yahoo on the second place (it is although needed to mark that the results of search on Yahoo very close coincide with the results of Altavista).
     Analysing the change of results of search for 2 months it is possible to notice the row of facts:
1.Increase of number of documents, found the searching system Meta. It can testify that this searching system makes active indexation of new resources.
2.Increase of general number of documents, found in the Internet. It testifies to popularity of subject of my master's degree work.
3.At a search in English language for some queries the decline of number of the found documents notedly in the search engines of Google, Yahoo, Altavista. To my mind, it is conditioned that happened re-indexed bases of these sites and from it already not existing in a network sites were remote. I.e. now results of search will be more reliable, as will not contain "dead" links.
     Analysing the results of search, I came to the followings conclusions:
1.Most exact and meaningful results at a search the searching system of Google gives in the Internet.
2.At a search in the Russian segment of the Internet it is also possible to utillize the searching system Yandex, which can give out documents which are not given (or gives out not in the first rows) out by Google often.
3.At an information retrieval in a network the Internet very much vazhnno is correct drafting of searching query. If to spare it more attention, it is possible to get more exact and ponderable results at a search.
