Silly question about the search results from the search engine here.

Hello!
I am new here in Simulia learning community. I have a really silly question that I dont know how to open a specific search result from the search engine here. for example I search by key words and I find a good search result that I need to open to read all about it, but I only find a preview option, and whenever I click on the open button it just closes the preview window.
Thanks!
