sed option to delete two words within a file

Still having some trouble deleting firstword
First off, I want to say thank inpavan for the help. To answer inpavens question regarding what I am trying to delete, I am trying to delete two words within a file. The file is about 80 lines in length. I do not want to delete any line just the words discovery and named.
1. The sed 's/yourword//g' yourfile > newfile - To delte the words only worked to delete either word, but only one word at a time.
2. The use of sed 's/firstword.*secondword//g' filename worked only to delete the secondword, the first word was ignored.
I am trying to figure out how to delete two words at the same time.
Again thanks for the help.
