I was seeing search.adp, but I don't now how I implement it in my search.
I only need that when I press the button "search" in my aplication, the words of my search, highlight with another color or format.
Please can you explain me, how can I do that. Thanksss.
I've not done this before myself, but your best bet might be to search and rewrite the text in the ADP, wrapping the search query in a div with CSS.
Take another look at search.tcl/.adp. It's already done there, so you might as well start with that.
Hope that helps.
