Eks Dev commented on LUCENE-3918:
---------------------------------
this is the right way to give some really good meaning to venerable optimize
call :)
We were, and are sorting our data before indexing just to achieve exactly this,
improvement in locality of reference. Depending on data (has to be somehow
sortable, e.g. hierarchical structure, on url...), speedup (and likely
compression Adrian made) gains are sometimes unbelievable...
> Port index sorter to trunk APIs
