As a result of detailed analysis, it was noted that the search engine Aport significantly inferior to other search engines in English-language queries.

9 months later I was made another search on the topic of master's work. Analysis of the search results showed that the search engine Google has given the greatest number of results in Russian, Ukrainian and English. But there are exceptions. For example, a query such as "transfer function" in search engines Yandex and Rambler exceeded the result of more than 20 times. These search engines also showed good results in the Russian-language queries. The worst result showed Bot Aport.

Comparing the results of 06.12.2010 and 18.03.2010 can note a significant improvement of results in search engines Yandex and Rambler. The remaining search engines showed no significant changes.
