Hi Gary,
I think for cts:element-value-query, you can do a starts-with by taking the
string the user gives and appending "* *" to it. This is because, for values,
* by itself matches can span tokens. For example, this query returns true:
let $x := <foo><a>this is a value</a></foo>
return
cts:contains($x,
cts:element-value-query(xs:QName("a"), "t* *", "wildcarded") )
I'd have to scratch my head a little for a contains with element-value-query,
but I think you can do something similar and it could work. Something like
this for "is a v":
let $x := <foo><a>this is a value</a></foo>
return
cts:contains($x,
cts:element-value-query(xs:QName("a"), "* *is a v* *", "wildcarded") )
So in this case, you prepend and append a "* *" to the string the user
supplies. I am not positive I have thought this one through though, although
it seems to work in the simple case.

Hi Gajanan,
Thanks for the suggestions. cts:field-word-query() is producing accurate
results as a 'contains' query, using a '*value*' matcher. Having a
'starts-with' query would be a nice to have feature in my application but not
critical.

Have you looked at cts:word-query with phrase-through/phrase-around?
If you want to look at particular elements, you can also define a field on
these elements and cts:use field-word-query.
Thanks,
Gajanan

Subject: [MarkLogic Dev General] wildcarding in constraining query
I'm attempting to create both 'starts-with' and 'contains' queries (for a
constraining query) on element values which needs to work across word
boundaries.
cts:element-value-query() does not wildcard across word boundaries and
cts:element-word query() only matches on single words. cts:element-value-match
does what I need but does not return a cts:query. Are there any other options
I have not looked at?
Thanks,
gary
