当您使用 XQuery 3.0 时，一个快速的解决方案是按条目 ID 进行分组，无论如何您都在解决这个问题：

(: snip :)
for $hyperlemma in $hyperlemmas
let $entry_id := $hyperlemma/ancestor::entry/@xml:id
group by $entry_id
let $lemma := $hyperlemma/ancestor::entry/lemma/orth
let $variant := $hyperlemma/ancestor::entry/variant/orth
return
  (: snip :)

一个更优雅的解决方案（但几乎导致完全重写查询）是循环遍历条目元素，并为每个找到第一个匹配项并打印它。

entry当可以在不同的位置找到给定的搜索词时，我终于弄清楚了如何在标签内打印某些元素。这是重写的 XQuery 代码（目前）对我有用并给出了预期的结果：

xquery version "3.0";
declare namespace output = "http://www.w3.org/2010/xslt-xquery-serialization";
declare option output:method   "xml";
declare variable $searchphrase := "ἄγγελος";
<html>
    <head>
        <meta HTTP-EQUIV="Content-Type" content="text/html; charset=UTF-8"/>
    </head>
    <body>
        <h1>Output of searchterm</h1>
        <p>You are looking for "<font color="red"><strong>{$searchphrase}</strong></font>"</p>
        {
        let $hyperlemmas := doc("sample_entry.xml")/(descendant::entry | descendant::cit)/hyperlemma/orth [contains(., $searchphrase)]
        let $ids := $hyperlemmas/ancestor::entry/@xml:id
        return
        <p>{$searchphrase} was found {count($hyperlemmas)} times. IDs: {data($ids)} </p>
        }
        {   
        let $entry_base := doc("sample_entry.xml")/text

        for $entry in $entry_base/entry
        let $id := $entry/@xml:id
        let $variant := $entry/variant/orth
        let $found_pos1 := $entry/hyperlemma/orth
        let $found_pos2 := $entry/descendant::cit/hyperlemma/orth
        where $found_pos1 = $searchphrase or $found_pos2 = $searchphrase
        return
        <div>ID {data($id)}:<br/>Lemma: {$entry/lemma/orth}<br/>
            {
            for $item in $variant
            return
            <div>Variant: {$item}
                {
                for $cit in $item/../cit/lemma
                where exists($cit)
                return
                <i>-> {$cit}</i>
                }
            </div>
            }
        </div>
        }
    </body>
