I know we can say {'avwI' vInej} for "I search for the guard". Meaning "I'm trying to locate him". But could the same sentence {'avwI' vInej} mean as well "I search the guard"? Meaning, "I search him in order to see if he is armed" ?

No, it wouldn’t. nej is glossed as “look for, seek, search for”. E.g. vInejqa' I am resuming the search. I am searching for him/her again.
