Hi Zhenjian YU         Means Now I have 2 options 1.    WildCardQuery 2.       PrefixQuery A] If I use WildCardQuery it will search “a” in whole word and then return result       e.g If I type “a” then it will return all results which contain “a” in their spelling. But I want when user type “a” it will show only “America” & “Asia” And when I type “as” then it will show only “Asia”. Does WildCardQuery has that capacity to do? Because this will send query to search engine as “a*” and “as*” ……   B] I think so PrefixQuery will do it. Because It will search for those terms in index who has “a” or “as” as prefix.   Thanks           Hi Vikas,   Seems that you can use the WildCardQuery to do this, just put "a*" as the query term. But take caution to use WildCardQuery, because it can bring the performance of your system down.   Yes, you can also implement your own filter to filter out the results which don't starting with "a".   Either way is a solution.   Best Regards, Zhenjian   On 5/24/06, Vikas Khengare <[EMAIL PROTECTED]> wrote: >  >  >  > Hi Zhenjian YU >  >  >  >       I have implemented that with AJAX Search But when I type "*a*" > in textbox.
