Hi Ambika,
The cts:frequency function takes only one value. Function mapping may be
active, resulting in an implicit flowr loop for each value-match value, making
your expression return a sequence of frequencies instead of a single summed
frequency count.
Function mapping can be very confusing, so I recommend disabling it by putting
the following line in the header of your XQuery:
declare option xdmp:mapping "false";
That will cause MarkLogic Server to complain about your expression. You need to
rewrite your expression as follows to make it work:
sum(
for $value in cts:element-value-match(xs:QName("name"), "Annie*") [1 to 10]
return
cts:frequency($value)
)
The sum function cumulates the individual frequency counts, making sure you get
a single total..
Kind regards,
Geert

Hi all,
I am running the cts:element-value-match query, I understand that indexes will
be created for each unique value in the element 'name'. But is it possible to
customize the indexing like creating a same index for Annie, Ánnie and Ànnie.
So that if i perform cts:element-value-match query like
cts:element-value-match(xs:QName("name"), "Annie*") [1 to 10]
lets consider, if i have '3' matches for Annie in element 'name' and
'1' match for Ánnie in element 'name and
'2' matches for Ànnie in element 'name' in the database.
cts:frequency(cts:element-value-match(xs:QName("name"), "Annie*") [1 to 10])
Then performing the above query should return result of 6 (summing the
individuals - Annie(3),Ánnie (1)m,Ànnie (2)). I also tried options of
cts:element-value-match query still without any changes to the indexes i am not
able to achieve this result.
Thanks in advance,
Regards,
Ambika

You mention that you are trying to count element names. But the query you are
using seems to find all the elements named "name" whose value starts with
"Annie".
Please clarify: what do you want to count exactly?
Also do you have a range index of type "string" set on the element named
"name"? Basically the function element-value-match() simply reads all the
values in the range index which match pattern "Annie*".
Thanks,
Gajanan

Subject: [MarkLogic Dev General] Reg: Diacritic-insensitive lexicons
Hi all,
I am trying to get the count of element names using the query
cts:element-value-match(xs:QName("name"),
"Annie*",("case-insensitive","collation=http://marklogic.com/collation/","diacritic-insensitive";)
)[1 to 10]
I am using cts:frequency of the above query to get the results.
For this i want values of Ánnie and Ànnie to match this query using
diacritic-insensitive option as the third parameter of element-value-match
query. But i am not getting results for this query as expected.
Should the collation be changed from root collation to unicode collation to get
this done?
Regards
Ambika
