Google said in its quest to create the perfect search engine, it cannot afford to rest on its laurels.
The company’s comments came at an event billed as a "state of the union" on search as it unveiled new products that aim to push search in a new direction.
Google has over 63% of the US market compared to rival Yahoo with 20%.
Google said users are becoming more sophisticated at search
"The race in search is far from over and innovation and continued improvement is absolutely pivotal," said Google’s Marissa Mayer.
"I’ve said this many times but search is still in its infancy. Our engineers are worried about what is the next big thing in search and how are they going to find it," said Ms Mayer who is the vice president of search products and user experience.
She said last year Google released over 365 products and in the first quarter of this year it was 120. Ms Mayer added that this was proof that "Google gets better all the time."
