Google introduced an advanced search feature that sorts the web results into basic, intermediate and advanced results last week.
The new search classifies the results into three categories and caters to people who are searching for fundamental information, elaborate information and technical information respectively.
The search company's new feature is yet another way for people to trim down their results to the kinds of pages they are most interested in, a Google representative stated.
Teachers looking for teaching material for their students or researchers looking for detailed technical information for their academic papers may find this feature useful, the search company said.
Google had hired teachers to develop the new classification system that sorts web pages into three levels.
