Hi Anshu, Can you also show the code of using cts:element-value-query directly?
Do documents in the database contain multiple titles, or always just one?

However, it returns doucments which include title element with following value Reviews of Physiology, Biochemistry' and 'Reviews of Physiology Biochemistry'. Let me know in case you need more info.

The result contains items with , and without , in the search term, e.g: "Reviews of Physiology Biochemistry" "Reviews of Physiology, Biochemistry" I have tried the same search with cts:element-value-query and that works perfectly fine and gives the results for the exact string value passed(either with , or without ,) as title. I also tried to resolve this with changing string range index root collation to unicode collation but didn't get any joy. Please Advice!

Unfortunately, I no longer have the output for that query (and I've changed the index so it uses "Unicode Codepoint"), so I can't share the exact codepoints any more but I can assure you they were identical :) Cheers, -Steve On 06/06/2011 17:02, Jason Hunter wrote: I'm curious what string-to-codepoints() shows for those two strings.

I've also tried using the explicit option "item-order" and adding a matching default collation to the prolog of the query. What's interesting is that doing a cts:frequency() on the two "Pia, H.W." values gives different numbers when doing the frequency lookup as part of the same query (e.g. in a FLOWR). However, when searching for the matching documents by string value in an XPath I only get one of the frequencies. It is as if one of the values in the list is completey bogus. I am confused :( -Steve On 06/06/2011 09:52, Ron Hitchens wrote: Does it behave the same way with an explicit collation option on the call to cts:element-attribute-values that matches the one in the range index definition? http://developer.marklogic.com/pubs/4.2/apidocs/Lexicons.html#cts:element-attribute-values On Jun 6, 2011, at 9:29 AM, Steve Mallen wrote: Hi folks, I have another mystery for the lexicon experts :) I've been fetching values out of a string attribute range index in item order and processing them a batch at a time. But I have noticed that occasionally I get duplicate values out of the index. This is causing conflicting updates (since I use the URI-encoded name as the basis for document URIs and insert many documents per query). I would have expected the cts:element-attribute-values() to return a list of unique string values - I don't really want to have to do fn:distinct-values() over them, and wouldn't have thought this necessary. I have checked the exact character strings returned by the function and they are identical - I checked this by doing a string-to-codepoints() on the suspect values. Here is an example of what I'm calling and getting back from the server: cts:element-attribute-values(xs:QName('lexi'), xs:QName('formatted_name'), "Pia, H.", ("limit=50")) Pia, H. W. Pia, Hans Werner Piacente, V. Piacente, Vincenzo Piacenti, Marcello Piacentini-Sorbi, Sylvia Piacentini, A. Piacentini, Dario Piacentini, Giuseppe Piacentini, I. Piacentini, John C. Piacentini, Leonardo Piacentini, Lucia Piacentini, M. Piacentini, Mauro Piacentini, Paola Piacentino, Filippo Piacentino, G. Piacere, A Piačková, Veronika Piacquadio, A. M.

Pia, Hans Werner Pia, Julius Pia, M. G. Pia, S. Notice that "Pia, H.W." is returned from the top of the list and also near the bottom. Now this suggests to me that either: a) There is only one value in the index and the function call is returning it twice in different locations. or b) There are actually two values in the index, but they are somehow being normalised and returned as the same string value. I am using the "Root Collation" for the range index. Could that be the issue? This seems like it may be a bug to me, but perhaps I'm doing something silly.
