search for one word and exclude another word in vim

In vim, to find all the lines containing the word 'condition' (without the quotes) and to exclude those lines containing 'condition number', install the LogiPat plugin available at http://vim.sourceforge.net/scripts/script.php?script_id=1290

The sample command looks like

:LP "condition" & !"condition_number"
