Hi. I get some strange results for one query from SOLR. This is an example query:
<str name="q"> (titolo:trenti OR sommario:trenti OR occhiello:trenti OR testo:trenti) </str> In the results I have this document: <result name="response" numFound="1" start="0" maxScore="6.5818048"> <doc> <float name="score">6.5818048</float> <str name="id">503af94e0c342</str> <str name="occhiello">IL PROGETTO.......... (no word "tren" in "occhiello" field) </str> <str name="sommario"/> <str name="sottotitolo"> C'รจ la concessione edilizia. Gli islamici... </str> (no word "tren" in "sottotitolo" field). <str name="testo"> La fine del ramadan, pochi giorni fa....... </str> (no word "tren" in "testo" field). <str name="titolo">Moschea in viale.....</str> (no word "tren" in "titolo" field). </doc> </result> This document does not have the word "tren" in any of the fields titolo, occhiello or testo, but: <lst name="highlighting"> <lst name="503af94e0c342"/> </lst> So, as I can see, this document was selected for the field "id". This is the debug: <lst name="explain"> <str name="503af94e0c342"> 6.5818048 = (MATCH) sum of: 6.3718405 = (MATCH) weight(id:503af94e0c342 in 48107), product of: 0.57440555 = queryWeight(id:503af94e0c342), product of: 11.09293 = idf(docFreq=1, maxDocs=48343) 0.05178123 = queryNorm 11.09293 = (MATCH) fieldWeight(id:503af94e0c342 in 48107), product of: 1.0 = tf(termFreq(id:503af94e0c342)=1) 11.09293 = idf(docFreq=1, maxDocs=48343) 1.0 = fieldNorm(field=id, doc=48107) 0.20996419 = (MATCH) product of: 0.83985674 = (MATCH) sum of: 0.83985674 = (MATCH) weight(titolo:trent in 48107), product of: 0.34054396 = queryWeight(titolo:trent), product of: 6.5765905 = idf(docFreq=182, maxDocs=48343) 0.05178123 = queryNorm 2.4662213 = (MATCH) fieldWeight(titolo:trent in 48107), product of: 1.0 = tf(termFreq(titolo:trent)=1) 6.5765905 = idf(docFreq=182, maxDocs=48343) 0.375 = fieldNorm(field=titolo, doc=48107) 0.25 = coord(1/4) </str> </lst> The field "id" is an indexed string field: <field name="id" type="string" indexed="true" stored="true" required="true" /> Could you help me to understand this behavior well, please? Thank you very much! Bye, Mattia.
