Still can't really understand you.....
Try using a different translator!
Try :

Possibly, you may have meant : that on doing a search in "Help" (.chm,
..hlp....etc.) you don't see anything highlighted.
Try :
1). "Clicking" on "Set search options" (Help and Support Center) and make
sure that the checkbox : "Turn on search highlight" IS ticked, and, that
the checkboxes below named "Search in title only" are NOT checked.
.....or,
2). Try changing the color for "selected items" in :
"Display Properties" - "Appearance" - "Advanced" (button)
....to a different color (one of the basic 16).
