• Use new DocSet/Scorer API 💬 by Caio 5 years ago

  Introduced on tantivy.git @ e25284ba
  
  This changeset is sufficient, however upstream's f71b04acb introduced
  a `debug_assert!(self.doc() <= target)` for `SegmentPostings::seek`
  that looks overzealous to me.
  
  In release mode all tests pass, but given that lot has changed since
  last I looked I'll be double checking the affected functionality
  prior to letting this go wild.
  

• Replace `map -> unwrap_or` with `map_or` by Caio 6 years ago
• Add initial DisMaxQuery implementation 💬 by Caio 6 years ago

  I was (unintentionally?) made aware that tantivy doesn't have a dismax
  query when @jackdoe pointed me at his cool new project. So I wrote one.
  
  Since I'm hacking on a dumb query parser that allows multiple fields
  and boosts, this will come in handy very soon.
