      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 := '';
&lt;results&gt;
{
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 $score descending
return
&lt;result score="{$score}"&gt;
 &lt;continente&gt;{$continente}&lt;/continente&gt;
 &lt;paese&gt;{$hit/../../../text()}&lt;/paese&gt;
 &lt;regione&gt;{$hit/../../text()}&lt;/regione&gt;
 &lt;provincia&gt;{$hit/../text()}&lt;/provincia&gt;
 &lt;cap&gt;{$cap}&lt;/cap&gt;
 &lt;nome&gt;{$hit/text()}&lt;/nome&gt;
&lt;/result&gt;
}
&lt;/results&gt;
executed through RESTFULL with the URL
http://localhost:8984/basex/jax-rx/comuni?wrap=no&run=fulltext_wildcards...
and follow the query results:
&lt;?xml version="1.0" encoding="UTF-8"?&gt;&lt;results count="6"&gt; &lt;result score="1"&gt; &lt;continente&gt;EUROPA&lt;/continente&gt; &lt;paese&gt;ITALIA&lt;/paese&gt; &lt;regione&gt;LAZIO&lt;/regione&gt; &lt;provincia&gt;FROSINONE&lt;/provincia&gt; &lt;cap&gt;03020&lt;/cap&gt; &lt;nome&gt;GIULIANO DI ROMA&lt;/nome&gt; &lt;/result&gt; &lt;result score="1"&gt; &lt;continente&gt;EUROPA&lt;/continente&gt; &lt;paese&gt;ITALIA&lt;/paese&gt; &lt;regione&gt;LAZIO&lt;/regione&gt; &lt;provincia&gt;VITERBO&lt;/provincia&gt; &lt;cap&gt;01034&lt;/cap&gt; &lt;nome&gt;FABRICA DI ROMA&lt;/nome&gt; &lt;/result&gt; &lt;result score="1"&gt; &lt;continente&gt;EUROPA&lt;/continente&gt; &lt;paese&gt;ITALIA&lt;/paese&gt; &lt;regione&gt;LAZIO&lt;/regione&gt; &lt;provincia&gt;ROMA&lt;/provincia&gt; &lt;cap&gt;00063&lt;/cap&gt; &lt;nome&gt;CAMPAGNANO DI ROMA&lt;/nome&gt; &lt;/result&gt; &lt;result score="1"&gt; &lt;continente&gt;EUROPA&lt;/continente&gt; &lt;paese&gt;ITALIA&lt;/paese&gt; &lt;regione&gt;LAZIO&lt;/regione&gt; &lt;provincia&gt;ROMA&lt;/provincia&gt; &lt;cap&gt;00020&lt;/cap&gt; &lt;nome&gt;CERVARA DI ROMA&lt;/nome&gt; &lt;/result&gt; &lt;result score="1"&gt; &lt;continente&gt;EUROPA&lt;/continente&gt; &lt;paese&gt;ITALIA&lt;/paese&gt; &lt;regione&gt;LAZIO&lt;/regione&gt; &lt;provincia&gt;ROMA&lt;/provincia&gt; &lt;cap&gt;00045&lt;/cap&gt; &lt;nome&gt;GENZANO DI ROMA&lt;/nome&gt; &lt;/result&gt; &lt;result score="1"&gt; &lt;continente&gt;EUROPA&lt;/continente&gt; &lt;paese&gt;ITALIA&lt;/paese&gt; &lt;regione&gt;LAZIO&lt;/regione&gt; &lt;provincia&gt;ROMA&lt;/provincia&gt; &lt;cap&gt;001xx&lt;/cap&gt; &lt;nome&gt;ROMA&lt;/nome&gt; &lt;/result&gt; &lt;/results&gt;for each result node you can see the score node with the same value for deferents &lt;nome&gt; nodes strings.Sorry for my English, and thanks for any comment.
