Processing wild-cards

  • Query mon* can now be run as

    • $m AND mo AND on


  • Gets terms that match AND version of our wildcard query.

  • But we’d enumerate moon.

  • Must post-filter these terms against query.

  • Surviving enumerated terms are then looked up in the term-document inverted index.

  • Fast, space efficient (compared to permuterm).
