--------------------------------------
Resolution: Fixed
> Use index hint not honored for AND predicates when CBO is on
> ------------------------------------------------------------
>
> Key: ASTERIXDB-3162
> URL: https://issues.apache.org/jira/browse/ASTERIXDB-3162
> Project: Apache AsterixDB
> Issue Type: Bug
> Components: COMP - Compiler
> Affects Versions: 0.9.6
> Reporter: Vijay Sarathy
> Assignee: Vijay Sarathy
> Priority: Major
>
> This is a fragment of CH2 query 6. This issue is reproducible with similar
> queries on non-CH2 tables also and happens with both array and non-array
> indexes.
> {code:java}
> SELECT count(*) as revenue
> FROM orders o, o.o_orderline ol
> WHERE ol.ol_delivery_d /*+ use-index (orderline_delivery_d) */ >=
> '2016-01-01 00:00:00.000000'
> AND ol.ol_delivery_d /*+ use-index (orderline_delivery_d) */ < '2017-01-01
> 00:00:00.000000';
> {code}
> The hint is honored when there is only a single predicate with no ANDs. The
> problem happens because the hint is not placed on the condition (as it is
> done for single predicates), but the condition has an "arguments" field which
> has the annotation. To fix this, we need to check the "arguments" field of
> the condition for the annotation.
