Please note that scoring propagation was removed with {{Mark|Version 9.5}}. The following expressions will now yield {{Code|0}}: <syntaxhighlight lang="xquery">let $string := 'a b'return ft:score($string contains text 'a' and $string contains text 'b'), for $n score $s in db:open('factbook')//religions[text() contains text 'orthodox']order by $s descendingreturn $s || ': ' || $n</syntaxhighlight> Scoring is still supported within full-text expressions, by {{Function|Full-Text|ft:search}}, and by simple predicate tests that can be rewritten to {{Function|Full-Text|ft:search}}:
The reason for removing the scoring propagation was that the storage of scoring values required additional memory, even if scoring is not required.

Fuzzy search is based on the Levenshtein distance. The maximum number of allowed errors is calculated by dividing the token length of a specified query term by 4. The query above yields two results as there is no error between the query term “house” and the text node “house”, and one error between “house” and “hous”.
A user-defined value can be adjusted globally via the {{Option|LSERROR}} option or, since {{Version|9.6}}, via an additional argument:
