How can i make the abstract field to case insensitive?

I want to search in the abstract field with the word which may have variables, eg, "XML", "xml", "Xml". It seems case insensitive search can work in the title field, but it cannot work in the abstract field!

Thanks a lot!

The Fast Search is

The Fast Search is case-insensitive. If you want to limit the search to Abstract field, please read my reply of your other post at http://support.biblioscape.com/node/1047. You can also use the Advanced Search to built a query to search "XML" or "Xml" or "xml" by clicking on the word "and", then change it to "or". You can then save this query as a search folder for later use.

Paul, thanks
