Hi Danny,
cts:element-value-match() will return the Value of the element "Surname". My
requirement need the element "Surname" itself. Please let me know how to
compose the cts:element-value-match() to get the element. I tried in the
following way
cts:search(fn:collection("UserDetails")//User,
cts:and-query((
cts:element-value-match(xs:QName("Surname"), "J*")
))
)
Please suggest the alternate way.I also tried with range query. I am getting
the
"XDMP-EXPNTREECACHEFULL" error.
cts:search(fn:collection("UserDetails")//User,
cts:and-query((
cts:element-range-query(xs:QName("Surname"),">=","A"),
cts:element-range-query(xs:QName("Surname"),"<","B")
))
Regards,
Mano

Hi Mano,
In your original email, you say you need to display a list of names that match
a
pattern. Similar to Szabolcs’ suggestion of using a range query, you can use
the lexicon functions which just return the values from the range index. And
range indexes are fast. cts:element-value-match is probably what you want.
Something like:
cts:element-value-match(“xs:QName(“Surname”), “J*”)
You can also pass this a cts:query if you want to constrain the lexicon look-up
to fragments that match a query.
You should only need to use cts:search if you want your results in relevance
order.
Hope that helps,
-Danny

Hi,
What about using element-range-query, like:
cts:search( fn:collection("UserDetails")//User,
cts:and-query((
cts:element-range-query(xs:QName(" Surname"),">=","S"),
cts:element-range-query(xs:QName(" Surname"),"<","T")
))
)
You need to setup a string range index on Surname

Hi Mano,
You could do fn:collection("UserDetails")//User//Surname[fn:starts-with(‘J’,
.)], but I don’t really expect that to be faster than using the wildcard option
of the query. Could even be that above expression is optimized to your query.
Kind regards,
Geert

Onderwerp: [MarkLogic Dev General] Alternate for wildcard search
Hi,
In my application I have to display the list user name starts with the
character
choosen by the User. In the ML database all the Wildcard options are disabled.
I
have enabled the Wildcard in cts:element-word-query() directly , which slow
down
the query execution. Is there anyother way to get the user names starts with
specific character?
Sample query:
cts:search (fn:collection("UserDetails")//User,
cts:element-word-query(xs:QName ("Surname"),"J*",
"wildcarded"))
Regards,
Mano
