Hello all,
i am trying to tune our core for exact matches on a single field (itemNo) and having issues getting it to work. in addition - i need help understanding the output from debugQuery=on where it presents the scoring. my goal is to get exact matches to arrive at the top of the results. however - what i am seeing is non-exact matches arrive at the top of the results with MUCH higher scores. // from schema.xml - i am copying itemNo in to the string field for use in boosting <field name="itemNoExactMatchStr" type="string" indexed="true" stored="false"/> <copyField source="itemNo" dest="itemNoExactMatchStr"/> // from solrconfig.xml - i have the boost set for my special exact match field and the sorting on score desc. <requestHandler name="itemNoProductTypeBrandSearch" class="solr.SearchHandler" default="false"> <lst name="defaults"> <str name="defType">edismax</str> <str name="echoParams">all</str> <int name="rows">10</int> *<str name="qf">itemNoExactMatchStr^30 itemNo^.9 divProductTypeDesc^.8 brand^.5</str>* <str name="q.alt">*:*</str> * <str name="sort">score desc</str>* <str name="facet">true</str> <str name="facet.field">itemDescFacet</str> <str name="facet.field">brandFacet</str> <str name="facet.field">divProductTypeIdFacet</str> </lst> <lst name="appends"> </lst> <lst name="invariants"> </lst> </requestHandler> // analysis output from debugQuery=on here you can see that the top socre for itemNo:9030 is a part that does not start with 9030. the entries below (there are 4) all have exact matches - but they rank below this part - ??? <str name="0904000,1354 ,<b>2TTZ9030C1000A* "> 0.585678 = (MATCH) max of: 0.585678 = (MATCH) weight(itemNo:9030^0.9 in 582979), product of: 0.021552926 = queryWeight(itemNo:9030^0.9), product of: 0.9 = boost 10.270785 = idf(docFreq=55, maxDocs=594893) 0.0023316324 = queryNorm 27.173943 = (MATCH) fieldWeight(itemNo:9030 in 582979), product of: 2.6457512 = tf(termFreq(itemNo:9030)=7) 10.270785 = idf(docFreq=55, maxDocs=594893) 1.0 = fieldNorm(field=itemNo, doc=582979) </str> <str name="1220000,1232 ,<b>9030* "> 0.22136548 = (MATCH) max of: 0.22136548 = (MATCH) weight(itemNo:9030^0.9 in 499864), product of: 0.021552926 = queryWeight(itemNo:9030^0.9), product of: 0.9 = boost 10.270785 = idf(docFreq=55, maxDocs=594893) 0.0023316324 = queryNorm 10.270785 = (MATCH) fieldWeight(itemNo:9030 in 499864), product of: 1.0 = tf(termFreq(itemNo:9030)=1) 10.270785 = idf(docFreq=55, maxDocs=594893) 1.0 = fieldNorm(field=itemNo, doc=499864) </str> <str name="0537220,1882 ,<b>9030 *"> 0.22136548 = (MATCH) max of: 0.22136548 = (MATCH) weight(itemNo:9030^0.9 in 538826), product of: 0.021552926 = queryWeight(itemNo:9030^0.9), product of: 0.9 = boost 10.270785 = idf(docFreq=55, maxDocs=594893) 0.0023316324 = queryNorm 10.270785 = (MATCH) fieldWeight(itemNo:9030 in 538826), product of: 1.0 = tf(termFreq(itemNo:9030)=1) 10.270785 = idf(docFreq=55, maxDocs=594893) 1.0 = fieldNorm(field=itemNo, doc=538826) </str> <str name="0537220,2123 ,<b>9030 *"> 0.22136548 = (MATCH) max of: 0.22136548 = (MATCH) weight(itemNo:9030^0.9 in 544313), product of: 0.021552926 = queryWeight(itemNo:9030^0.9), product of: 0.9 = boost 10.270785 = idf(docFreq=55, maxDocs=594893) 0.0023316324 = queryNorm 10.270785 = (MATCH) fieldWeight(itemNo:9030 in 544313), product of: 1.0 = tf(termFreq(itemNo:9030)=1) 10.270785 = idf(docFreq=55, maxDocs=594893) 1.0 = fieldNorm(field=itemNo, doc=544313) </str> <str name="0537220,2087 ,<b>9030 *"> 0.22136548 = (MATCH) max of: 0.22136548 = (MATCH) weight(itemNo:9030^0.9 in 544657), product of: 0.021552926 = queryWeight(itemNo:9030^0.9), product of: 0.9 = boost 10.270785 = idf(docFreq=55, maxDocs=594893) 0.0023316324 = queryNorm 10.270785 = (MATCH) fieldWeight(itemNo:9030 in 544657), product of: 1.0 = tf(termFreq(itemNo:9030)=1) 10.270785 = idf(docFreq=55, maxDocs=594893) 1.0 = fieldNorm(field=itemNo, doc=544657) </str> -- View this message in context: http://lucene.472066.n3.nabble.com/need-help-with-getting-exact-matches-to-score-higher-tp3983882.html Sent from the Solr - User mailing list archive at Nabble.com.
