Hi Shai, So one follow-up question.
Assume that my use case is to have approx. ~50M documents indexed with each document having about ~10-15 indexed but not stored fields. These fields will never change, but there are another ~5-6 fields that will change and will continue to change after the index is written. These ~5-6 fields may also be multivalued. The size of this index turns out to be ~120GB. In this case, I would like to sort or facet or search on these ~5-6 fields. Which approach do you suggest? Should I use BinaryDocValues and update using IW or use either a ParallelReader/Join query. ----------------------- Thanks n Regards, Sandeep Ramesh Khanzode On Tuesday, July 1, 2014 9:53 PM, Shai Erera <ser...@gmail.com> wrote: Except that Lucene now offers efficient numeric and binary DocValues updates.
