Subject Re: any example on FunctionScoreQuery since Field.setBoost is deprecated with Lucene 6.6.0
Date Tue, 31 Jul 2018 23:59:04 GMT
Robert,

thanks, this is helpful but why did this change when it was great to 
use? SortField is a new concept to me  and i am not sure this is avail 
in 6.6.0 but will check.

This new way seems more tricky.

if there are more examples, i will be happier :)

Best regards
