Hi,
I have a query which is optimized in a curious way in BaseX 9.0.2 (yesterday's snapshot).
This is the original query:
xquery version "3.1"; declare namespace tei ="http://www.tei-c.org/ns/1.0"; let $string := "string" let $fuzzy := false()
return ( collection('ZK')/tei:TEI[ if (false()) then (.[descendant::text() contains text {$string} using fuzzy]) else (.[descendant::text() contains text {$string}]) ], collection('ZK')/tei:TEI[ if ($fuzzy) then (.[descendant::text() contains text {$string} using fuzzy]) else (.[descendant::text() contains text {$string}]) ] )
And this is the optimized one (newlines inserted by me for better readability):
( ft:search("ZK", "string" using language 'English')/ancestor::tei:TEI[parent::document-node()], ft:search("ZK", "string" using fuzzy using language 'English')/ancestor::tei:TEI[parent::document-node()] )
I'm curious why the second search is using fuzzy, even though the variable $fuzzy is false. I presume that query optimization is independent of the data, so you won't need the data to reproduce. But if you do, I can provide it. A database with enabled full-text index is required obviously.
