OpenKM has many interesting features, but requires some configuration process to show its full potential.
Forum rules: Please, before asking something see the documentation wiki or use the search feature of the forum. And remember we don't have a crystal ball or mental readers, so if you post about an issue tell us which OpenKM are you using and also the browser and operating system version. For more info read How to Report Bugs Effectively.
First of all I would like to know which OpenKM version are you using. We are working in a new OpenKM Community release and we need feedback. Please, try to reproduce the issue with a recent nighbuild from http://integration.openkm.com/6.2/ .
I am currently struggling with this issue, too.
On Version 6.3.7 (build: 3fc09ed) the search is case sensitive, which makes is quite difficult for the users. Where can I change the configuration to have a case insensitive search?
