Mikhail Krupitskiy updated CASSANDRA-12573:
-------------------------------------------
    Description: 
Cassandra 3.7.

Experiment 1:
{noformat}
drop keyspace if exists kmv;
create keyspace if not exists kmv WITH REPLICATION = { 'class' : 'SimpleStrategy', 'replication_factor':'1'} ;

use kmv;

CREATE TABLE if not exists kmv (id int primary key, c1 text, c2 text);

CREATE CUSTOM INDEX ON kmv.kmv  ( c2 ) USING 'org.apache.cassandra.index.sasi.SASIIndex' WITH OPTIONS = {
 'mode': 'CONTAINS'
};

insert into kmv (id, c1, c2) values (1, 'f21', 'qwe') ;
insert into kmv (id, c1, c2) values (1, 'f22', 'qweasd') ;
insert into kmv (id, c1, c2) values (1, 'f23', 'qwea1') ;
insert into kmv (id, c1, c2) values (1, 'f24', '1qwe') ;

select c2 from kmv.kmv where c2 like '%w%a%';
{noformat}
Expected result: qweasd, qwea1.
Actual result: no rows.


Experiment 2:
{noformat}
drop keyspace if exists kmv;
create keyspace if not exists kmv WITH REPLICATION = { 'class' : 'SimpleStrategy', 'replication_factor':'1'} ;

use kmv;

CREATE TABLE if not exists kmv (id int primary key, c1 text, c2 text);

CREATE CUSTOM INDEX ON kmv.kmv  ( c2 ) USING 'org.apache.cassandra.index.sasi.SASIIndex' WITH OPTIONS = {
 'mode': 'CONTAINS',
 'analyzer_class': 'org.apache.cassandra.index.sasi.analyzer.StandardAnalyzer',
 'analyzed': 'true'
};

insert into kmv (id, c1, c2) values (1, 'f21', 'qwe') ;
insert into kmv (id, c1, c2) values (1, 'f22', 'qweasd') ;
insert into kmv (id, c1, c2) values (1, 'f23', 'qwea1') ;
insert into kmv (id, c1, c2) values (1, 'f24', '1qwe') ;

select c2 from kmv.kmv where c2 like '%w%a%';
{noformat}
Expected result: qweasd, qwea1.
Actual result: 1qwe.

  was:
Cassandra 3.7.

1) Create index for String column:
{noformat}
CREATE CUSTOM INDEX index_name ON Table (Column) USING 'org.apache.cassandra.index.sasi.SASIIndex' WITH OPTIONS = {'mode': 'CONTAINS'};
{noformat}
2) Insert some rows where Column contains 'foo' and 'bar'. E.g. '1foo2bar3'.

3) Try to query rows where Column contains 'foo' and 'bar'.
Request {noformat}select * from Table where Column like '%foo%bar%'{noformat} returns *no* rows.
