Google has made changes to its algorithms to make it easier for users to find more relevant results, as the changes are aimed to better understand "associations and concepts related to your search," offering related search results on the same page, the search giant announced on its blog Tuesday.

For searches three words or longer, a snippet from the relevant page will tell the user whether the page is worth looking at, by highlighting the words from the search in bold on the page.

The Orion Search technology that Google acquired in 2006 helps users find concepts related to the meaning of the search word, BusinessWeek reported.

Microsoft has also purchased a similar startup, called Powerset, last year. Last but not the least, Yahoo has been using its Search BOSS "to offer other Web developers ways to use its technology to create custom search engines." These ventures, however, have had "limited success."
