The length limit of the address parameter is too strict

[Mini256]

Describe the bug

In GeocodeQuery, the constraints limit the parameter address length. In fact, many Chinese place names only need two words to describe.

For example, 杭州 means Hangzhou city, its length is only 2, but this is a valid address.

Maybe there are some place names in other languages also short.
