Is it possible to sort ignoring case?

My X-Query looks something like this:
/A/B sortall(…/name)

and I’d like it to return items in a case-insensitive order.

It does not appear that I can include any functions in the sortall clause, otherwise I could fake case insensitivity with a translate function (assuming Tamino supports the translate function).

Thanks!

Hi,

In the schema editor for TSD3 and TSD4 schemas you can define a Collation on the name field. If you specify a collation and a suitable collation language (I used “en_GB”) you can affect the physical sequence in which the sorted values are returned.

HTH.

Sorry, I have this question too…

I change the Collation to “yes” in Tamino’s Schema Editor and change the Collation language to “en_GB” and then define the schema again to an existing database, not work. Do I need to unload and reload all the data?

I still get “AIDS” sorted ascendingly before “Accidents”. Can anyone teach me in a more detail way?

Thank you very much!

You need to recreate index using the _admin command
Finn

So, can you post how to recreate the index??

I can’t find any documentation about _admin command, I know nothing about it.

Thanks!

Have a look in the documentation in the chapter:
“Requests using X-Machine Commands”

_admin=ino:RecreateIndex
which of course takes some parameters
be aware that there is both a RecreateIndex and a RecreateTextIndex function.

Thank you very much Finn! Get it works now…

But after then, I can’t use [subject between ‘A’, ‘A~’] as posted below,

the query return no data…

Thanks a lot!!

Hi Lun,
Can’t quite figure out which query you mean ?
Finn

Hi,

In more precise, I have a normal field “subject” that I used to use the query
/article[subject between ‘A’, ‘A~’] to find all the elements that start exactly with a ‘A’. Due to the sorting issue described in this thread, I modified the field to Collation=“yes” and Collation Language=“en_GB”, I fixed the sorting issue.

But after then, I found that my query “/article[subject between ‘A’, ‘A~’]” return no data (it’s working well before I modified the Collation setting). I have already tried RecreateIndex and RecreateTextIndex, still not work.

Because the query "/article[subject ~= ‘A*’] will include result like “You And Me”, I have started another thread
http://tamino.forums.softwareag.com/viewtopic.php?p=8289
to ask help previously.

Best regards,
Lun
