found a working solution
for using the hit highlighter.

And if possible if you can give any examlpe
Thanks in advance!

| Hi
I think ASP.net may not affect the hit highlighter.
It is accessed by putting parameters in the URL address.
http://msdn2.microsoft.com/en-us/library/ms692928.aspx
is the documentation for webhits.dll, with examples ...

don't use the highlighter, built your own one ...
1) Define a new CSS-Class which makes the text highlighted (i.e. yellow
background)
2) Write a function to change your search-results ...
3) in your results HTML-Code let the function enlose your search-phrase
with your new CSS-tag
works fine, is fast & short

THE FUNCTION:
Function Highlight(Search_Str as String, InputTxt as String, StartTag as
String, EndTag as String) As String
Return Regex.Replace(InputTxt, "(" & Regex.Escape(Search_Str) & ")",
StartTag & "$1" & EndTag, RegExOptions.IgnoreCase)
End Function
THE FUNCTION CALL:
MyHigLightedHTMLCode = Highlight(MySearchString, MyHTMLCode, "<span
class=highlight>", "</span>")

why not (or maybe I did not understand)? The point is, that you highlight
the search phrase in the query's result(!).
If you use ASP.NET you should have and therefore control the result string
no matter what query-technique you use. Search & replace the search-phrase
and that's it.
We use it in different projects.

| search on mouse with a freetext query and your content has mouse and mice in
it. How are you going to mark up mice?

thank you, I understand (and didn't understand before as I already feared).
Now it's evident that our 'technique' does only work with simpler animals
than mice ;-)
