I need to perform search in an html page displayed in a UIWebView control. The functionality I need is something that Safari has, when you hit command/ctrl F for searching the document for some word and the program highlights the hits for you. Is there any easy solution for this problem?
I know it's been a long time since you asked this question, but it's still a pretty common question people have so I put together a sample project in case anyone else is asking the same question. The project is a super simple app that loads an HTML file and can search and highlight any keyword. You can download the sample project here:

Edit: changed link above as the old one had broken.
You could do this with javascript. Check out the "Find in this page" bookmarklet: http://www.lifeclever.com/17-powerful-bookmarklets-for-your-iphone/
Something like that, combined with: http://developer.apple.com/iphone/library/documentation/uikit/reference/UIWebView_Class/Reference/Reference.html#//apple_ref/occ/instm/UIWebView/stringByEvaluatingJavaScriptFromString:
might do the trick.
