Case insensitive search

[Moe]

I'm using XSLT to search a field named 'email' that contains email addresses, and I want it to be a case insensitive search. I've already set up the field to convert all letters to lowercase.

I could use javascript to convert the field input to lowercase on submission, but I'd like to avoid using javascript.

Anyone have any ideas?

Thanks.

I assume the field is indexed as Unicode.

It could go along the following line:

- pass the field input as token instead as a search field, and do some dummy action with form

- on the next page, read out the token in the request-query parameter and store it in a variable search

- translate the variable with

- do now a search with the XSLT document() function
