David Smiley reopened LUCENE-533: --------------------------------- Re-opening; this is definitely not done. > SpanQuery scoring: SpanWeight lacks a recursive traversal of the query tree > --------------------------------------------------------------------------- > > Key: LUCENE-533 > URL: https://issues.apache.org/jira/browse/LUCENE-533 > Project: Lucene - Core > Issue Type: Bug > Components: core/search > Affects Versions: 1.9 > Reporter: Vincent Le Maout > Priority: Minor > > I found the computing of weights to be somewhat different according to the > query type (BooleanQuery versus SpanQuery) : > org.apache.lucene.search.BooleanQuery.BooleanWeight : > public BooleanWeight(Searcher searcher) > throws IOException { > this.similarity = getSimilarity(searcher); > for (int i = 0 ; i < clauses.size(); i++) { > BooleanClause c = (BooleanClause)clauses.elementAt(i); > weights.add(c.getQuery().createWeight(searcher)); > } > } > which looks like a recursive descent through the tree, taking into account > the weights of all the nodes, whereas : > org.apache.lucene.search.spans.SpanWeight : > public SpanWeight(SpanQuery query, Searcher searcher) > throws IOException { > this.similarity = query.getSimilarity(searcher); > this.query = query; > this.terms = query.getTerms(); > idf = this.query.getSimilarity(searcher).idf(terms, searcher); > } > lacks any traversal and according to what I have understood so far from the > rest > of the code, only takes into account the boost of the tree root in > SumOfSquareWeights(), > which is consistent with the resulting scores not considering the boost of > the tree > leaves. > vintz -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
