                 Key: ORC-980
                 URL: https://issues.apache.org/jira/browse/ORC-980
             Project: ORC

The current SArg to Filter Conversion ignores the case-sensitivity setting during read and always perform case-sensitive search of fields leads to exceptions such as
{quote}java.lang.IllegalArgumentException: Field RIDX not found in struct<f1:bigint,f2:decimal(20,6),f3:bigint,f4:string,ridx:bigint>
