Many queries are ambiguous, for instance: ‘design’, ‘cars’, ‘sports’, etc. These queries are called ‘informational’. The best result for such a query would be a selection of links to the resources representing different meanings of the query. Thus, the output for the query "design" should contain links to the websites on web-design, landscape design, interior design, etc.

It is not easy to compile a high-quality multi-thematic set of links, especially considering the fact that site optimizers abuse popular informational queries to promote their customers' sites. Due to such SEO-"pressing", the top is taken over by resources whose promotion is most profitable, so the results become monotonous, consisting of websites with the same kind of commercial offers.
