As the web search is used for every possible need, it is vital that a search engine be able to find meaningful answers to most diverse questions. This ability depends both on the search engine's scope and on its interpreting potential.

These analyzers reflect the two above-mentioned aspects of the search engines' functioning, the quantity of the output and its diversity (when allowed by the non-strict sense of the query). To keep the results valid, we regularly put to test our set of queries.
It is worth noting that since the information that cannot be retrieved by means of a search engine is in some sense unattainable, the relative values in these analyzers are in no way less important than the absolute ones.
