-----------------------------------
One more thing because you are active contributor, [~planka]. :)
- The default branch of Apache ORC is `main`, not `master`. So, please use
`1.8.0` instead of `master`.
- Apache ORC intentionally avoids *some words* as you see in our dev mailing
list.

> Project: ORC
> Issue Type: Bug
> Components: Java
> Affects Versions: 1.7.0, 1.8.0
> Reporter: Pavan Lanka
> Assignee: Pavan Lanka
> Priority: Blocker
>
> The current SArg to Filter Conversion ignores the case-sensitivity setting
> during read and always perform case-sensitive search of fields even when
> asked to perform case-insensitive match using
> {quote}options()
> .searchArgument(sarg{color:#cc7832}, new {color}String[]
> {{color:#6a8759}"RIDX"{color}})
> .allowSARGToFilter({color:#cc7832}true{color})
> .isSchemaEvolutionCaseAware({color:#cc7832}false{color}){quote}
> leading to the following exceptions that the field is not found in the schema
> {quote}java.lang.IllegalArgumentException: Field RIDX not found in
> struct<f1:bigint,f2:decimal(20,6),f3:bigint,f4:string,ridx:bigint>
