Hello everybody

Thanks to your help Christian, our full text queries yet work fine.

I still don't understand exactly what the problem was and why we got 500 internal errors.

Maybe a too heavy query and thus a memory problem ?

Anyway now with this kind of writing, the queries are completed :

declare function desanti:display-tags($collection, $dataType, $mode){  
                               let $label := if($dataType = "subject") then "concepts" else "personnes"
  return <div class="{ $mode }">
    <h6>{ $label }</h6>
    <span>{
      for $term in $collection
      group by $term
      order by $term collation "?lang=fr"
      let $occurrences := count(
        ft:search('Desanti', $term)/..[local-name() = $dataType][
          parent::*:controlaccess/
          parent::*:c/
          ancestor::*:dsc/
          parent::*:archdesc/
          parent::*:ead/
          parent::document-node()
        ]
      )
      return if($mode = "cloud") then (
        <span><a style="font-size:{
          $occurrences idiv 10 + 1
        }em;padding:{
          $occurrences idiv 10
        }px;" title="{
          $occurrences
        }" href="/restxq/desanti/{$label}/{$term}">{$term}</a></span>
      ) else (
        <span class="{
          $occurrences
        }"><a href="/restxq/desanti/{$label}/{$term}">{ $term }</a>
          ({ $occurrences })
        </span>
      )
    }</span>
  </div>
};

Thanks a lot !!!
