delete lines that match pattern but

I have a script that delete all lines in a given file that has two patterns present, nameX and surnameX for example. The problem is that sometime in other fields further in the line the nameX can appear and it deletes the line also

nameX surnameX sdkflfjffsl sdlfjsd flsdkjsdjf sdlfdf > ok to delete

nameY surnameY ddsfdsfsfsf sf sdfdfdfdsfdsf fdf fsdf > keep line

nameY surnameX dfdsfsffsfsdf fsfsdfsff nameX fdsfffs > deletes, but i dont wat it to. How to proceed ?

My code is below

awk '$0!~v1 || $0!~v2' v1="nameX" v2="surnameX" /home/oldfile > /home/newfile

Help would be appreciatted :)
