Writing custom predicate to handle case insensitive use cases for grouped queries in AEM

so I have an AEM query that looks like this:

nodename=master
group.p.or=true
group.1_property=title
group.1_property.value=%article%

group.2_property=body
group.2_property.value=%article%
group.1_property.operation=like

Now this gives me all the results where the property contains article but not if it contains Article or aRticle etc.

I would want to know if there's already an inbuilt predicate like `[13:46] Sahil, Shivam Oh okay actually I want to make a group query case insensetive: nodename=mastergroup.p.or=truegroup.1_property=titlegroup.1_property.value=%article% group.2_property=bodygroup.2_property.value=%article%group.1_property.operation=like

So this gives me result wherever the title contains article however not if it contains Article or aRticle etc etc

I want to know if we already have a predicate for which I can add something like: group.1_property.caseSenstivity=false

otherwise I would be interested in extending property predicate one like:

        log.debug("Generated query: {}", query);
        return query;
    }
} 

Can someone help me extending property predicate to caseInsensetiveProperty predicate where I can also specify if the search should have case insenstivity or not?
