I'm a little confused about what you say.  Do you mean when i click one
point , it's just ask for a query?

because i think query is just i type in some word, and then something happen
to look up in some tables.

I look through your suggestion and the URL you gave me , but found no
example as i asked.

i think it's very popular application , maybe someone has realized before.
I'm a beginner, so maybe i misunderstand what you say.
