Hi guys,
I was wondering about the following.
I ran the following XQuery against a very large collection (+- 16k documents)
****************************************************************************
let $btIds := ("BLF3G22-30","BLF3G22-30","BLF2043","BLF2043","BLF2045")
(: Remark in my case the list above took 20k identifiers :)
for $btId in $btIds
where empty(index-scan('basictype_id', $btId, 'EQ'))
return $btId
****************************************************************************
But the index-scan function returns the document where I'm actually already
satisfied with knowing if the value is present in the index. I did not see any
function that returns a Boolean however (if $value in index).
Does this have a severe performance penalty I was wondering?
Robby
