Subject [Lucene-java Wiki] Update of "SummerOfCode2011ProjectRankingNotes" by DavidNemeskey
Date Mon, 13 Jun 2011 11:37:27 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Lucene-java Wiki" for change notification.

The "SummerOfCode2011ProjectRankingNotes" page has been changed by DavidNemeskey:

   * sumOfSquaredWeights: a weighted squared average, but why include idf (the "weight", in
both meanings)? What about similarities that have no idfs?
  === TODOs ===
-  * idf is used outside of Similarity in MultiPhraseWeight, PhraseWeight, SpanWeight, TermWeight
+  * idf is used outside of `Similarity` in `MultiPhraseWeight`, `PhraseWeight`, `SpanWeight`,
-  * computeStats should not be exposed, either
+  * to do sth about `Weight.explain()`:
+   * what is weight (see above)?
+   * explanation for similarities, maybe separated into "weight"/not weight (per doc?) part?
