    Ok, I suppose you want to search inside a web page very much like what cntrl+f provides.
    So this can be done by using java-script. For a demo, make a html file, paste in the following code and check how will it work.

    <html>
    <head>
    </head>
    <body>
    my name is amit yadav, type amit to search
    <script>

        var TestRange = null;

        var nom = navigator.appName.toLowerCase();
        var agt = navigator.userAgent.toLowerCase();
        var is_major   = parseInt(navigator.appVersion);
        var is_minor   = parseFloat(navigator.appVersion);
        var is_ie      = (agt.indexOf("msie") != -1);
        var is_ie4up   = (is_ie && (is_major >= 4));
        var is_not_moz = (agt.indexOf('netscape')!=-1)
        var is_nav     = (nom.indexOf('netscape')!=-1);
        var is_nav4    = (is_nav && (is_major == 4));
        var is_mac     = (agt.indexOf("mac")!=-1);
