Description of the search algorithm
Search engine allows you to create queries based on a keyword or phrase:
Request like Patent Organization returns links to documents that contain either the word "patent" or the word "organization".
Query as a phrase that is enclosed in quotation marks, for example "Patent Organization" returns links to documents containing the complete phrase "patent organization".
Search is case sensitive. This means that when you query for the word "patent", and when prompted for the word "Patent" will produce different results.
