It seems that the latest version of Maxthon has had some updates done to the built-in search bar. I've taken the plunge and started using it instead. The one thing I was missing from the built-in search bar before this version was the keyword which are put on the Google bar automatically whenever I perform a search making it easy to find the words in a particular page. Maxthon now has this capability as well so there is really no reason for me to keep using the Google bar which sends all kinds of information back to Google, no need for the entire world to know my preferences in pr0n :)
Another great feature of the built-in toolbar relates to my last post about shortcuts in Maxthon, specifically to the CTTL + SHIFT + F shortcut which takes you to the search field, I've been missing this in the Google bar.
Also be aware that you can add your own search engines to the built-in search making it easy to access just about any search engine on the net, just as long as they support passing the query in the URL.
You may also be interested in knowing that there is an option for search an entire list of search engines all at once, something which has been available for some time in stand-alone search programs.
