Subject Re: [jira] Resolved: (JCR-198) jcr:contains doesn't return incomplete match
Date Fri, 26 Aug 2005 09:47:20 GMT
Indeed, it works.
Thanks for your answer.

The following query doesn't work :

//*[jcr:contains(., '*bi*')]

Why is it so ?

+ [node] node1
        [prop] title = "a new question"
+ [node] node2
        [prop] title = "answer"


Basically, my need is to do the following search :
   - search for a string anywhere in a property. For example, with the 
contents above, searching for 'N' should return both nodes.
   - case insensitive

So jcr:like(%title, "%N%") do the job but is case sensitive. And 
jcr:contains(%title, "*N*") is not possible.
I'm stuck here.

Do you have an idea ?
