Re: Use of SortComparator.getComparable() ?

Dear all,

I'm recently implementing a sort logic that leverages an external index,
however, I'm confused by the newComparator() and getComparable() in
SortComparator.

It seems natural to me that IndexSearcher -> FieldSortedHitQueue ->
factory.newComparator().  However, what's the use of getComparable() if
newComparator() is doing the job?  Any use scenario?

Thanks
Tea

Hi all,

Just digging deeper.. It seems the Custom comparables used in newComparator
comes from getComparable(), right?

Thanks
Tea
