Insensitive search using query builder

Hi,

I want to convert below sql query so as to use for querybuilder .

select * from nt:unstructured where jcr:path like '/content/dam/company/project/data/%' and UPPER(ctn_no) LIKE 'HD%' or UPPER(family_name) LIKE 'HD%' order by jcr:score desc

I tried with below values from querybuilder component.

type=nt:unstructured

path=/content/dam/company/project/data

group.1_property=ctn_no

group.1_property.value=HD%

group.1_property.operation=like

group.p.or = true

group.2_property=family_name

group.2_property.value=HD%

group.2_property.operation=like

orderby=jcr:score

orderby.sort=desc

To do a case insensitive search, I am always converting input parameter to upper case so I can match that parameter with the value from CRX.

Please guide me if I am in right direction and how can I do case insensitive search using querybuilder with above approach.

Thanks,
