I have shot a short film with boom pole and shotgun mic, the voice (comes up from actors) is pretty clear, but I'm not very satisfied.
Is there anything I can do more to eliminate this wind/background noise while shooting?

If there's nothing I can do, perhaps I can do it in post (like with sound soap or some kind)?

How do you accomplish very clear sound like hollywood movies?

You didnt say if your shotgun mic had a windshield or not because if it didnt then you need to get one to cut out the wind for much clearer sound in the future. That doesnt matter now though because you have already shot it so cant change that. However i am pretty sure there will be some sound programs to cut out this ambient sound - it might effect the quality of the sound though i dont know youll need someone else to anwser as i havent had this problem too much.

If it is not the whole scene that is affected and ownly certain shots then you could do what Robert Rodriguez did with El Maraichi and re-record the dialougue and insert it on a reaction shot.

Hope you find a solution

Professional sound recordists and mixers use several methods. The
good news is everything they do in Hollywood, we as indie
filmmakers can do.

During the recording get the mic as close as you can to the
actors. Lower the pick up volume and have them speak louder. That
way you get a higher signal (dialogue) to noise (ambiance) ratio.
A good boom operator is very important - just as important as the
camera you use but something few filmmakers pay much attention to
- and they listen very carefully to the audio being recorded.
They will catch any ambient problems before you get into the
editing room.

But about 70 to 90 percent of all dialogue recorded in Hollywood
movies is done after production - in a studio. This is called
?looping? or ADR - additional dialogue replacement. They do this
for several reasons. On most all movies with effects there is way
too much noise on set to get clear dialogue tracks. But mostly
they loop everything because of foreign language dubbing.

Studios are required to deliver a music and effects (M&E) track.
That?s everything but the dialogue. So if, for example, there are
footsteps, or a door closing or even the subtle rustling of
clothing on the dialogue track that needs to be separated for the
foreign language dub. So almost all dialogue is recorded in a
studio after the shoot.

We can do that too. Though it?s harder with less experienced
actors. One thing I do is have the actors record some lines right
there on set if the sound recordist thinks there may be a problem
later. No video recorded just the actor, close to the mic, saying
a line or two.
