The only workaround using the int index that I could think of would be to use
ranges with range-queries. Something like:
let $pattern := 200
return cts:or-query((
for $i in 0 to 10
let $power := xs:int(math:pow(10, $i))
let $start := $pattern * $power
let $end := ($pattern + 1) * $power
return cts:and-query((
cts:element-range-query(xs:QName("element"), ">=", $start),
cts:element-range-query(xs:QName("element"), "<", $end)
))
))
Cheers

Hi Oleksii,
You'll have to create a string range index too. I've never used
cts:element-value-match() with anything but a string index, but it looks like
it's possible: you just get back the value you asked for, if it exists. And now
that I think about it, that can be rather useful! So thanks for effectively
cluing me in to this use case! :-)
The docs for the $pattern parameter say: "The parameter type must match the
lexicon type. String parameters may include wildcard characters."[1]
So that seems to confirm that wildcards can only be used with string-typed
range indexes.

Christopher,
It gives false positives if I use it with cts:element-values.
Shan,
The rule is to find all values which start with given value. For example, 200
should match 200, 2001, 2002, ... 20010, 20020, 2002123, etc..
Are you suggesting to guess all possible combinations? If so, it's not possible.
As I said, I need something like this (pseudo code):
cts:element-value-match(xs:QName("element"), "200*")
except that I don't have a string range index on that field, but I do have an
int range index instead.
Best,
Oleksii.

What is your exact search rule? From your example, looks like you try to
look for another number by adding a ³0². If that is the case, can you run
a cts:or-query, one for 200, and one for 2000?
