The amount of information stored in the Web is huge and without help from search engines it becomes almost impossible to find what you want. The search engines try to index as many web pages as possible. On April 3rd 2018 there were over 45.5 billion webpages indexed by Google and just over 4 billion web indexed by Bing. Even with the help of search engines, the number of addresses of pages returned by them for a simple query is quite large and we, as people, must look through those pages to find what we are really interested in. Finding the URLs in such a huge data space is challenging and requires some special techniques for refining and reducing the number of returned addresses. In our paper we present some interrogation modifiers and search operators used by the Google search engine to reduce significantly the number of the search results and to increase the quality of that results. The presented techniques and commands for search engines that can be used for finding similar web pages or even to find web pages which repeat information from another sources.
