Re: LTR - OriginalScore query issue
>From Apache Solr tests : loadFeature( "SomeEdisMax", SolrFeature.class.getCanonicalName(), "{\"q\":\"{!edismax qf='title description' pf='description' mm=100% boost='pow(popularity, 0.1)' v='w1' tie=0.1}\"}"); *qf='title description'* Can you try again using the proper expected syntax ( with single quotes). If it doesn't work we may need to raise it as a bug.

Re: LTR - OriginalScore query issue
Yes, I have tried that too: But it was throwing error while feature extraction: "Exception from createWeight for SolrFeature [name=originalLuceneScore, params={q={!dismax qf=tem_type_all^30.0 ..}${user_query}}] Failed to parse feature query. at org.apache.solr.ltr.LTRScoringQuery.createWeights(LTRScoringQuery.java:241) at org.apache.solr.ltr.LTRScoringQuery.createWeight(LTRScoringQuery.java:208) at org.apache.solr.ltr.response.transform.LTRFeatureLoggerTransformerFactory$FeatureTransformer.setContext(LTRFeatureLoggerTransformerFactory.java:245) at org.apache.solr.response.transform.DocTransformers.setContext(DocTransformers.java:69) at org.apache.solr.response.DocsStreamer.(DocsStreamer.java:89) at org.apache.solr.response.ResultContext.getProcessedDocuments(ResultContext.java:55) at org.apache.solr.response.TextResponseWriter.writeDocuments(TextResponseWriter.java:260) - --Ilay -- Sent from: http://lucene.472066.n3.nabble.com/Solr-User-f472068.html
Re: LTR - OriginalScore query issue
I understood your requirement, the SolrFeature feature type should be quite flexible, have you tried : { name: "overallEdismaxScore", class: "org.apache.solr.ltr.feature.SolrFeature", params: { q: "{!dismax qf=item_typel^3.0 brand^2.0 title^5.0}${user_query}" }, store: "myFeatureStoreDemo", } Cheers - --- Alessandro Benedetti Search Consultant, R Software Engineer, Director Sease Ltd. - www.sease.io -- Sent from: http://lucene.472066.n3.nabble.com/Solr-User-f472068.html
Re: LTR - OriginalScore query issue
I do have the features defined as below for field specific (title..) matching etc: features: [ { name: "productNewness", class: "org.apache.solr.ltr.feature.SolrFeature", params: { q: "{!func}recip( ms(NOW,launchdate_pl), 3.16e-11, 1, 1)" }, store: "myFeatureStoreDemo", }, { name: "originalScore", class: "org.apache.solr.ltr.feature.OriginalScoreFeature", params: null, store: "myFeatureStoreDemo", }, { name: "productTitleMatchGuestQuery", class: "org.apache.solr.ltr.feature.SolrFeature", params: { q: "{!dismax qf=p_title}${user_query}" }, store: "myFeatureStoreDemo", } ] What I am looking for is the original score for that document given the query (efi.user_query) before re-ranking i.e. as per the "qf" defined in the request handler - that matches different fields with the query: qf=item_typel^3.0 brand^2.0 title^5.0 - --Ilay -- Sent from: http://lucene.472066.n3.nabble.com/Solr-User-f472068.html
Re: LTR - OriginalScore query issue
>From the snippet you posted this is the query you run : q=id:"13245336" So the original score ( for each document in the result set) can only be the score associated to that query. You then pass an EFI with a different text. You can now use that information to calculate another feature if you want. You can define a SolrFeature : { "store" : "myFeatureStore", "name" : "userTextCat", "class" : "org.apache.solr.ltr.feature.SolrFeature", "params" : { "q" : "{!
LTR - OriginalScore query issue
solr/collection/select?fl=id,score,[features+store=myFeatureStore+efi.user_query='black shoes']=json=id:"13245336"=on When we fire this query during feature extraction, the originalScore feature gets the score of the "id" match but not the actual user query which is in this case 'black shoes'. The feature definition is in features.json: { "name":"originalScore", "class":"org.apache.solr.ltr.feature.OriginalScoreFeature", "params":null, "store":"myFeatureStore"} Is it the expected behaviour? I do not watch the tf/idf score for matching the id, rather I would want to match score for the query w.r.t. that item. - --Ilay -- Sent from: http://lucene.472066.n3.nabble.com/Solr-User-f472068.html
