次のxmlファイルがあります:
<?xml version="1.0" encoding="UTF-8"?>
<data>
<text>We are a doing nothing here you can say it time pass. what are you doing doing doing doing doing time?</text>
<text>We are a doing nothing here you can say it time pass. what are you doing doing doing doing doing time?</text>
</data>
今、私は次のクエリを実行しました:
let $hits :=
let $terms :=
let $node := xdmp:document-filter(doc("/content/C/Documents and Settings/vimleshm/Desktop/abc.xml"))
return
(cts:distinctive-terms($node,
<options xmlns="cts:distinctive-terms"
xmlns:db="http://marklogic.com/xdmp/database">
<use-db-config>false</use-db-config>
<score>logtf</score>
<max-terms>100</max-terms>
<db:word-searches>true</db:word-searches>
<db:stemmed-searches>off</db:stemmed-searches>
<db:fast-phrase-searches>false</db:fast-phrase-searches>
<db:fast-element-word-searches>false</db:fast-element-word-searches>
<db:fast-element-phrase-searches>false</db:fast-element-phrase-searches>
</options>)//cts:term)
for $wq in $terms
where $wq/cts:word-query
return element word {
attribute score { $wq/@score},
$wq/cts:word-query/cts:text/string() }
return
let $x:=
for $hit in $hits
return $hit
return $x
それは私に次の応答を与えます:
<?xml version="1.0" encoding="UTF-8"?>
