I have a client who uses a search form for a specific search, currently it will display 10 results at a time.  The users would like this increased to say 50 results at a time.  I was able to adjust the Search.aspx file but that didn't change the results.  I did verify that if I perform the same search from the search page it will now return 50 out of the 300+.  Can you adjust the results for Search Forms?
