Let's analyse results of search.

If to compare the first and second tables, it is visible, that, though has passed about two months, but the data have changed, and in the party of increase of amount of the found documents or pages.

Analyzing particularly given it is possible to see such dependences. As it is visible on first and on the fifth lines, the compression of the data uses the large popularity in environment Internet, that once again confirms a urgency of the chosen subject. And it is more sites in English on than tens thousand, that speaks about the large popularity or researches of this subject abroad, than at us. It is much less sites on ураинском than language, that is explained in unsufficiently large volume of a database. It proves to be true and результами on other searches in the Ukrainian language.

If to consider the tendency of productivity of retrieval systems, even on such small sample the appreciablly significant superiority of system Google. On sites in English with it(her) can compete Yahoo, and Russian resources well enough covers Rambler. Despite of apparently obvious orientation of a retrieval system Meta, Ukrainian sites it finds much less same Rambler.

The Line 7 at once induces an idea about incorrectivity of search, since all systems have given out a minimum quantity of results.
