To show a % rank next to a result, we exploit the ItemCreated event which will let us hook into the template creation and work with our own Label control (percentRank).
Assuming you already have 2 pages, one with SearchBox and the other with SearchResult - open the page holding SearchResult.
1. In the ResultItemTemplate in the SearchResult control, add a Label control, eg.
<ResultItemTemplate>
<TABLE border="0">
<TR>
<TD class="SEResultItemLink"><A href="<%# Container.Uri %>"><%# Container.Title %></A></TD>
</TR>
<TR>
<TD class="SEResultItemSummary"><%# Container.Summary%></TD>
</TR>
<TR>
<TD class="SEResultItemURL"><%# Container.Uri %></TD>
</TR>
<tr>
<td>
<asp:Label ID="percentRank" Runat=server></asp:Label>
</td>
</tr>
</TABLE>
<BR />
</ResultItemTemplate>
2. In the code-behind for the SearchResult page, add this field;
int topWeight=-1;
3. again in the code-behind, add the following code to the Page_Load method;
if(ViewState["topWeight"]!=null)
topWeight = (int) ViewState["topWeight"];
this.SearchResult1.ItemCreated+=new Keyoti.SearchEngine.Web.SearchResult.SearchResultItemEventHandler(SearchResult1_ItemCreated);
4. and add this method;
private void SearchResult1_ItemCreated(object sender, Keyoti.SearchEngine.Web.SearchResultItemEventArgs e)
{
//If we are showing a ResultItem (and not a header, footer or error)
if(e.Item is Keyoti.SearchEngine.Web.ResultItem)
{
//Grab the result weight from the underlying data, note ResultItem is in a different namespace to the ResultItem above
int weight = ((Keyoti.SearchEngine.Search.ResultItem) e.Data).Weight;
if(topWeight==-1) //this is the first result, so store it's weight
{
topWeight = weight;
ViewState["topWeight"] = topWeight;
}
//find our new label and set it to the %
Label percLabel = (Label) e.Item.FindControl("percentRank");
percLabel.Text= ((10000*weight)/(100*topWeight))+"%";
}
}
