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
