How to realize the function only a validator is fired when submit

Question

Sorry for my question.
In a web Page here are a inputText of a code ,a search button Searching by the Code , others inputText s and a 'OK ' button.
the question is how to fired a only 'code' validator when searching
I made the search button immediate="true" ,So I wanted to fire the code validator by actionListener, the others validator were not fired .
But in this way i find i can't get the code's number not only by binding
but also by value. so What shall i do?
the actionListener is this:
     public void commandButton_search(ActionEvent e){
          UIViewRoot UIroot=FacesContext.getCurrentInstance().getViewRoot();
          UIComponent uicomponent=UIroot;
          String strCode= (String)this.inputText1.getValue();
MemberValidator aValidator=new MemberValidator();
          aValidator.searchAddressCheck(uicomponent,strCode);

As I posted before a response for your post,
if you want to use the input value in an action,
you should not use immediate="true";
otherwise you need to do everything JSF will do.
The most simple way is to have two <h:form>s in the page.
One <h:form> includes the <h:inputText> of a code and the search button.
Another <h:form> includes other components.
If the OK button also use the seach code, you can use Javascript to copy the
code value from the <h:inputText> in the first form to some <h:inputHidden>
in the second form.
