Currently, if we use the ExplainAugmenterFactory with LtR, instead of using the model/re-rankers explain method, it uses the default query explain (tf-idf explanation). This happens because the BasicResultContext doesn't wrap the query(https://github.com/apache/lucene-solr/blob/1d85cd783863f75cea133fb9c452302 214165a4d/solr/core/src/java/org/apache/solr/response/BasicResultContext.java#L6 7) with the RankQuery when its set to context's query, which is then used by the ExplainAugmenterFactory. (https://github.com/apache/lucene-solr/blob/1d85cd783863f75cea133fb9c45230221416 5a4d/solr/core/src/java/org/apache/solr/response/transform/ExplainAugmenterFacto ry.java#L111). As a result there are discrepancies between queries like - http://localhost:8983/solr/collection1/select?q=*:*&collection=collectionName&wt =json&fl=[explain style=nl],score&rq=\{!ltr model=linear-model} http://localhost:8983/solr/collection1/select?q=*:*&collection=collectionName&wt =json&fl=score&rq=\{!ltr model=linear-model}&debugQuery=true the former outputs the explain from the SimilarityScorer's explain while the latter uses the correct LtR ModelScorer's explain. There are a few other problems with the explain augmenter - for eg. it doesn't work with grouping (although the other doc transformers like LtR's LTRFeatureLoggerTransformerFactory work with grouping) -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
