      CompanyViewBean.companyViewBean = new CompanyViewBean();
          CompanyViewBean.companyViewBean.subAction
    = new XML("<actionContext><actionName>SearchCompany</actionName></actionContext>"); var nameSearch:String = fComptxt.text; CompanyViewBean.companyViewBean.companyName=<name>{nameSearch}</name>;

1. if they typed fastly then get errors (http errors)
2. Is it any possible do any other way implement quick searching

If you can load up all the data at once, then you can use the sorting functionality of an ArrayCollection to filter data as the user types. It should be pretty quick.

But, if you want to ping the database after every keystroke, you're often going to have issues with lag time between server and client compared the speed of the user's typing.

I can see two options you might investigate:

1. You could disable the text input after every keystroke until you get data back from the server.
2. After each keystroke, You could cancel the "in process" remote request before starting the new one.
