I know hot to add a search tool on my site. My problem is that when an entry is found, I'd like to have the choice of continuing the search in the page for more entries of the same name.

Thanks !

You need to show us the code you are using for your search tool.

Ok here it is:

<script language="JavaScript">

var NS4 = (document.layers);    // Which browser?
var IE4 = (document.all);

var win = window;    // window to search.
var n   = 0;

function findInPage(str) {

  var txt, i, found;

  if (str == "")
    return false;

  // Find next occurance of the given string on the page, wrap around to the
  // start of the page if necessary.

  if (NS4) {

    // Look for match starting at the current point. If not found, rewind
    // back to the first match.

    if (!win.find(str))
      while(win.find(str, false, true))
        n++;
    else
      n++;

    // If not found in either direction, give message.

    if (n == 0)
      alert("Not found.");
  }

  if (IE4) {
    txt = win.document.body.createTextRange();

    // Find the nth match from the top of the page.

    for (i = 0; i <= n && (found = txt.findText(str)) != false; i++) {
      txt.moveStart("character", 1);
      txt.moveEnd("textedit");
    }

    // If found, mark it and scroll it into view.

    if (found) {
      txt.moveStart("character", -1);
      txt.findText(str);
      txt.select();
      txt.scrollIntoView();
      n++;
    }

    // Otherwise, start over at the top of the page and find first match.

    else {
      if (n > 0) {
        n = 0;
        findInPage(str);
      }

      // Not found anywhere, give message.

      else
        alert("Not found.");
    }
  }

  return false;
}

</script>
</body>

</html>
<p>&nbsp;<form name="search" onSubmit="return findInPage(this.string.value);">
<p align="center">
<font size=3><input name="string" type="text" size=15 onChange="n = 0;"></font><font face="Arial" size="4"><input type="submit" value="Search Page">

</font>
</form></p>

Ok...this is just a suggestion, but I don't think you want to use JavaScript here unless it is a last resort.

If I understand the general idea, you are trying to do a site about the horrific happenings in the USA.  You are going to have a very general audience.   Also, you are going to be using server side scripting for the posting part.....so why not use server side scripting for the search too?  It would be less reliant on the user having scripting enabled on their browser.

Just a suggestion.

May I suggest this script if you are sticking with Javascript.

http://www.infohiway.com/javascript/search/wildcard.htm

It will display all instances of a word and let the user choose which to go to.

I will stick with the ASP page. I'm not going to pick a database... I just need to know if there's such a thing?
