SortField.FIELD_SCORE
first...
Otherwise, generate all your scores and convert them
to sortable Strings at index time on your votes field.
Then, use this for
Hi Xiong,

Hi there,
Just like google: the more user clicks of search results,
the higher rank they are.

Hello,
This is not currently in Lucene.
Sounds like you are looking for a voting
system to generate float scores that would be
inserted as a sortable field at index time.
Gathering user feedback on search results is
hard because you need to introduce a layer
which logs the click then redirects
