Samsung S4 Google Browsing History

[Soph01]

Hi, I have been unable to access my browsing history when using google for sometime on my phone. You know when you would re type a search word you maybe had already searched for earlier and it remembers it - saves having to type and search all over again - well i've lost it! I did have to change my settings as my browsing history had linked up from my phone to pc that was shared - so really from there on i think is when the problem started. Can anyone suggest a way of getting it back as i cant remember what i did to change the privacy settings!
Thanks
