Needs to be Ported

  • make sure DistributedSearch builds and tests pass
  • Port Similarity
  • Port SpellChecker
  • Port WordNet
  • (optional) Port other contrib packages from java (some can't be easily


  • Contrib.Analyzers
  • Contrib.FastVectorHighlighter
  • Contrib.Queries
  • Contrib.Regex (there's an issue with one of the tests, it's been marked
    as ignored, has to do with a differences in the regex engines)
  • Contrib.Snowball
  • Contrib.Core/Contrib.SimpleFacetedSearch builds but looks to be .NET specific
  • No labels
