Thanks. Both the full title search and the match any word search turned up nothing.
Been there. What I do is to put the most unique word in the search bar by itself. In this case, it would have been either Hansen, Schmidt, or NASA. Then I pick through the pile to find if it has been posted. Hasn't failed me yet.
The Free Republic search features baffle me. I can never find anything no search. Not even things I posted and know is there.
Either I am terribly stupid or the search feature is not as useful as we need it to be.
