BlackBerry OS gives you the option of choice to choose what you want to search, but advice can confuse web search results that you should want. You can actually hide the web so as not to confuse the advice of your search.
You can hide the web advice by a simple way through the check box. To disable the web suggestions just go to head Options > Device > then tick the Show Web Search Suggestion.
By disabling the web advice, then you do not have to display the BlackBerry more web advice that can confuse you. Good luck.
