-------------------------------------------
Summary: LIKE query on clustering column index returns incorrect
results
Key: CASSANDRA-11397
URL: https://issues.apache.org/jira/browse/CASSANDRA-11397
Project: Cassandra
Issue Type: Bug
Reporter: Sam Tunnicliffe
Assignee: Sam Tunnicliffe
Fix For: 3.5
The way that {{ClusteringIndexFilter}} and {{RowFilter}} are constructed when a
{{LIKE}} restriction on a clustering column is present is incorrect. For
example:
{code}
cqlsh> create table ks.t1 (k text, c1 text, c2 text, c3 text, v text, primary
key (k,c1,c2,c3));
cqlsh> create custom index on ks.t1(c2) using
'org.apache.cassandra.index.sasi.SASIIndex';
cqlsh> select * from ks.t1;
k | c1 | c2 | c3 | v
---+----+----+----+-----
a | ba | ca | da | val
a | bb | cb | db | val
a | bc | cc | dc | val
(3 rows)
cqlsh> select * from ks.t1 where c1 = 'ba' and c3 = 'da' and c2 LIKE 'c%' ALLOW
FILTERING;
k | c1 | c2 | c3 | v
---+----+----+----+---
(0 rows)
{code}
