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.

==Thesaurus==
One or more thesaurus files can be specified in a full-text expression. The following query returns {{Code|false}}:

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, preserving a minimum of 1 errors. 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:
