Query:
xquery version "3.1"; declare namespace tei = "http://www.tei-c.org/ns/1.0"; let $string := "string" let $fuzzy := false() return ( collection('BIBL')/tei:TEI[ if (false()) then (.[descendant::text() contains text {$string} using fuzzy]) else (.[descendant::text() contains text {$string}]) ], collection('BIBL')/tei:TEI[ if ($fuzzy) then (.[descendant::text() contains text {$string} using fuzzy]) else (.[descendant::text() contains text {$string}]) ] )

Compiling:
- pre-evaluate fn:collection([uri]) to document-node() sequence: collection("BIBL") -> (db:open-pre("BIBL", 0), ...)
- rewrite if to iter filter: if(false()) then (.)[descendant::text() ... -> (.)[descendant::text() contains text { $...
- rewrite iter filter to ftcontains: (.)[descendant::text() contains text { $... -> descendant::text() contains text { $stri...
- rewrite iter filter to ftcontains: (.)[descendant::text() contains text { $... -> descendant::text() contains text { $stri...
- apply full-text index for { $string_0 } using language 'English'
- pre-evaluate fn:collection([uri]) to document-node() sequence: collection("BIBL") -> (db:open-pre("BIBL", 0), ...)
- inline $string_0
- inline $fuzzy_1

- rewrite iter filter to ftcontains: (.)[descendant::text() contains text "st... -> descendant::text() contains text "string...
- simplify gflwor

Optimized Query:
