> Assume that the schema for a data and index table is as follows:
> create table datatable (id varchar(10) not null primary key, val1 varchar(10), val2 varchar(10),
val3 varchar(10))
> create index indextable on datatable (val1) include (val2, val3)
> A query that filters rows on a covered column does not trigger the index read repair
for unverified index rows. For example, the following query will not trigger the read repair
> select val2, val3 from datatable WHERE val1 = 'ab' and val2 = 'abc'
