Case insensetive properties: AEM 6.5: Query Builder API

Hi,

As far as I know there is no native Query Builder Predicate for doing case insensitive queries. 

You can create a custom predicate for an application. 

Add the below code. The predicate works by lower casing the value and then using the XPath fn:lower-case method to compare to the field value in lower case.

        log.debug("Evaluating predicate: {}", predicate);
        String property = predicate.get(PREDICATE_PROPERTY);
        Locale locale = Optional.ofNullable(predicate.get(PREDICATE_LOCALE)).map(lt -> Locale.forLanguageTag(lt))
                .orElse(Locale.getDefault());
        String value = predicate.get(PREDICATE_VALUE).toLowerCase(locale).replace("'", "''");
        String query = String.format("fn:lower-case(@%s)='%s'", property, value);
        log.debug("Generated query: {}", query);
        return query;
    }
} 

Once the custom predicate is available in your application, it can be used in any Query Builder query as such:

path=/content/test
equalsIgnoreCase.property=test
equalsIgnoreCase.value=test
equalsIgnoreCase.locale=en_US

You can try with "Fulltext" search in querybuilder to get the list of all pages which contains certain string but if you want specific case sensitive then you need to have custom predicate to achieve the requirement
