[N1QL] array-indexing query hangs

basically these indexes are present:

CREATE INDEX nested_idx ON default( DISTINCT ARRAY ( DISTINCT array j for j in i end) FOR i in tasks END) USING GSI

CREATE INDEX idxtasks ON default( DISTINCT ARRAY x FOR x in tasks END) USING GSI

This is the query that was run:

explain select name from default WHERE ANY i IN default.tasks SATISFIES  (ANY j IN i SATISFIES j='Search' end) END AND (ANY x IN default.tasks SATISFIES x = 'Sales' END) AND  NOT (department = 'Manager') order BY name limit 10

Logs and backup will be attatched.

You can run this test to observe this behavior as well
