Today I cleaned chrome's cache and found it lost many other search engine , only left some.
I don't know where this other search engine gone and how them generated at first. But it is need much effort to set one by one.
I just wonder how can I get those other search engine back easily?
After some searching I found this Google Chrome automatically adding websites to my list of search engines?
Looks like this is a function built-in chrome.But after I access some website used to have custom search engine, Chrome didn't add search engine for them. none of them .
So I think it must something wrong with this function . I like this function, without it I have to add custom search engine by myself.
What should I do ?
