Dear Pablo,
final score values may be influenced by many side effects (use of index, document structure, etc.). To give you more info, we'd need to have a look on the original XML documents, or a little sample that allows us to reproduce the resulting score values. It would be great if you could provide us with a small example that runs out of the box.
Hope this helps, Christian

Hello community, I have a question about score results. I create a DB with one XML document using TF/IDF text node strategy and when make query on it always obtain the same score for all results equal one. the query is: declare option output:omit-xml-declaration "no"; declare variable $w1 as xs:string external := 'roma'; declare variable $w2 as xs:string external := '';
<results> { for $hit score $score in /kdo/idf/idf/idf/idf/idf[text() contains text {$w1} all words using wildcards ] let $cap := $hit/idf[@ctx="20.1"]/text() let $continente := $hit/ancestor-or-self::idf[@ctx="20.9"]/text() order by $score descending return <result score="{$score}"> <continente>{$continente}</continente> <paese>{$hit/../../../text()}</paese> <regione>{$hit/../../text()}</regione> <provincia>{$hit/../text()}</provincia> <cap>{$cap}</cap> <nome>{$hit/text()}</nome> </result> } </results> executed through RESTFULL with the URL http://localhost:8984/basex/jax-rx/comuni?wrap=no&run=fulltext_wildcards.xq&var=w1=roma and follow the query results:
<?xml version="1.0" encoding="UTF-8"?>
<results count="6"> <result score="1"> <continente>EUROPA</continente> <paese>ITALIA</paese> <regione>LAZIO</regione> <provincia>FROSINONE</provincia> <cap>03020</cap> <nome>GIULIANO DI ROMA</nome> </result> <result score="1"> <continente>EUROPA</continente> <paese>ITALIA</paese> <regione>LAZIO</regione> <provincia>VITERBO</provincia> <cap>01034</cap> <nome>FABRICA DI ROMA</nome> </result> <result score="1"> <continente>EUROPA</continente> <paese>ITALIA</paese> <regione>LAZIO</regione> <provincia>ROMA</provincia> <cap>00063</cap> <nome>CAMPAGNANO DI ROMA</nome> </result> <result score="1"> <continente>EUROPA</continente> <paese>ITALIA</paese> <regione>LAZIO</regione> <provincia>ROMA</provincia> <cap>00020</cap> <nome>CERVARA DI ROMA</nome> </result> <result score="1"> <continente>EUROPA</continente> <paese>ITALIA</paese> <regione>LAZIO</regione> <provincia>ROMA</provincia> <cap>00045</cap> <nome>GENZANO DI ROMA</nome> </result> <result score="1"> <continente>EUROPA</continente> <paese>ITALIA</paese> <regione>LAZIO</regione> <provincia>ROMA</provincia> <cap>001xx</cap> <nome>ROMA</nome> </result> </results>
for each result node you can see the score node with the same value for deferents <nome> nodes strings.
Sorry for my English, and thanks for any comment.
