Rule ->specific word in the body , can i create it?

@Catch-22 @skybat

hi
I switched to program in my native language and i found the solution

I suggest as a first step that your rule relies only on the header of your emails. FYI:

right !
Very wise ,just because i was used to click menu-> rules → new rule and there are some pre-made rules
where can i find the header ?

and please can i use the wildcards in the words in the body or sender adress or obeject ( for example ? or * )?

and when i click on the sender i have less rules and condition , for example words in the body ,why ?
if I use an outlook account even words less rules and condition

thanks

i think i will try and learn how to make powerfull rules
are all the rules and condition the same with a gmail or yahoo or outlook account?

about these request this , are these rules presents and available ?
thanks
