( CNN ) -- With Google Glass , a new quest to cure death and driverless cars , it can be easy to forget what Google 's primary business is : search . The largest search engine in the world is getting a few updates , the company announced on Thursday . Google tied the news to its 15th birthday and held the announcement in the original Google Garage . The overall design has been updated and borrows the `` card '' look from Google Now , lumping relevant information into rectangles and carousels and placing it above any links to websites . Answers will now be `` richer '' and include comparisons , filters and sorting . For example , if you ask Google to compare two foods , it will return a chart of their nutritional values . There are new results for song and music searches , and push notifications will soon come to the Google iOS app . The company is continuing to focus heavily on voice search , improving its conversational skills on the Web and in search apps . `` We believe that voice will be fundamental to building interactions with future devices that we will see , '' said Amit Singhal , Google 's senior vice president of search . Devices such as smartwatches and Google Glass forgo traditional input devices in favor of voice interactions . No corporate birthday party is complete without a trip down memory lane and balloons and birthday cake , both of which were also present at the event . In September 1998 , Google founders Larry Page and Sergey Brin started their company in Susan Wojcicki 's home garage in Menlo Park . The space remains largely unchanged and still has the same sky blue carpet Wojcicki had installed as a perk to persuade Brin and Page to rent the space . Wojcicki , now a senior vice president at Google , kicked off the event . `` Even though a lot of thing are different at Google , the core is still the same , '' she said , citing the company 's commitment to improving search , being a global company and thinking big . The original Google was indexing pages on the Internet , returning links to 10 Web pages that had a high probability of containing information that matched a query . The system was imperfect , easily flummoxed by synonyms , misspelled words and sites that gamed the system . Over the years , Google has launched various changes to the search engine to improve results . It added spell check , grasped the concept of synonyms and rolled out auto-complete . In 2007 , it moved on from just links and started including other types of relevant content such as images , news articles and maps as part of its `` universal search . '' A subtle update happened in 2010 . Google Instant shaved fractions of seconds off each Google search by predicting your search terms as you type them . `` Google gives me back an hour of my life every month , '' said Singhal of Google Instant . `` That 's not small , that 's huge . '' More recent changes have focused on how Google understands information . The Knowledge Graph debuted in 2012 and connects search terms with real objects , places and people . Now the company is indexing information . Instead of the top 10 pages about Picasso , you will get information on the painter directly from Google at the top of your search results , including background , images of famous paintings and related artists . People who use Google might not notice one of the bigger changes . The company has updated its under-the-hood search algorithms to something called `` Hummingbird , '' which will affect 90 % of searches worldwide . The changes will make a difference in how results are ranked . `` Finding relationships between concepts is a very , very hard problem . And you have to balance the meaning of what that query is looking for with what the document is saying , '' said Singhal .
