Sun Mar 6 13:00:00 2016 Patrick Frey 0.5.0-0.1
- add upperbound seek with upper key restriction to database interface (not used yet in storage)
- change return value of document term iterator skipDoc from boolean to document number
- more helpers for posting iterator implementations (just a start) and reorganize code in posting join operator iterators (eliminate copy paste code)
