How to Override executeQuery() in VOImpl.java for simple search

Question

Hi,
When I am going thorugh the dev guide I read that we can override the execute query to add more where conditions for a simple search with queryBean.
As per dev guide ,
If your view object's definition requires bind values, or you must manually append an unrelated WHERE clause every time the query is executed, you can proceed in one of two ways. In either scenario, OAFramework appends the user's search criteria to the WHERE clause immediately before executing the query,so any WHERE clause characteristics that you define are preserved.
1. Override the executeQuery() method in your *VOImpl to modify your WHERE clause and then call super.executeQuery(). This is recommended if you exercise the same logic every time the view object is queried.
2. Handle the generated Go button's press and call an initQuery() method on your view object where you can modify the WHERE clause and/or set bind values.
I didnt see the executeQuery() in my *VOImpl , am I missing anything here ? can you please help me to code the above ways of handling the execution.
I saw another exactly post in this forums and it didnt help much . (https://forums.oracle.com/thread/541807) .

Shobhit,
Thank you so much for your help .
I tried like you said and its working . Below is the code I used please correct me if I am wrong or  if there is a better way to do it.
In controller added the following code
OAApplicationModule am = pageContext.getApplicationModule(webBean);
        OADBTransaction oadbtransaction = am.getOADBTransaction();
        oadbtransaction.putTransientValue("vnumber", "000016161");
In VOImpl added the following code
import oracle.apps.fnd.framework.server.OAApplicationModuleImpl;
public void executeQuery()
        OAApplicationModuleImpl oaapplicationmoduleimpl = (OAApplicationModuleImpl)getApplicationModule();
        OADBTransaction oadbtransaction =   oaapplicationmoduleimpl.getOADBTransaction();
       String vnumber1 = (String)oadbtransaction.getTransientValue("vnumber");
        setWhereClause("segment1 = nvl(:1,segment1)");
        setWhereClauseParam(0, vnumber1);
        super.executeQuery();
And ran the page everything working fine .
I have couple of questions
1. Is "oadbtransaction.putTransientValue " places the value is transaction cache ? If so is that value available across multiple pages ?
2. I see there is another option for the above  using pageContext.putSessionValue and pageContext.getSessionValue, I am able to use the pageContext.putSessionValue in controller,
but I dont know how to use the pageContext.getSessionValue as I didnt see the pageContext in VOImpl and I tried to "import oracle.apps.fnd.framework.webui.OAPageContext" but still no use.
