Index created:
create index ix on default where y like "abc%\";

Query issued:
select x,y from default where x > 20 and y like "abc%\";

Document contents:

{ "x": 21, "y": "abctest" }

select * from system:indexes shows index created as:

{
"indexes":

{ * "condition": "(`y` like \"\")",* "datastore_id": "http://127.0.0.1:8091", "id": "f2d2f0cba1115e6", "index_key": [ "`x`" ], "keyspace_id": "default", "name": "iy", "namespace_id": "default", "state": "online", "using": "gsi" }

},

*Note that the index created is showing condition as empty "condition": "(`y` like \"\")" *

For same document, the below query gives correct results:
select x,y from default where x > 20 and y like \"abc%"
;
create index ix100 on default where y like "abc%";

Are the backward slashes ignored in query?
