| '''Summary'''
* Return all text nodes of the database {{Code|DB}} that contain the numbers {{Code|2010}} and {{Code|2020}}:<br/><code>ft:search("DB", ("2010", "2020"), map { 'mode': 'all' })</code>
* Return text nodes that contain the terms {{Code|A}} and {{Code|B|}} in a distance of at most 5 words:
<syntaxhighlight pre lang="'xquery"'>
ft:search("db", ("A", "B"), map {
"mode": "all words",
}
})
</syntaxhighlightpre>
* Iterate over three databases and return all elements containing terms similar to {{Code|Hello World}} in the text nodes:
<syntaxhighlight pre lang="'xquery"'>
let $terms := "Hello Worlds"
let $fuzzy := true()
let $dbname := 'DB' || $db
return ft:search($dbname, $terms, map { 'fuzzy': $fuzzy })/..
