> Key: ASTERIXDB-2674
> URL: https://issues.apache.org/jira/browse/ASTERIXDB-2674
> Project: Apache AsterixDB
> Issue Type: Bug
> Components: *DB - AsterixDB, AQL - Translator AQL, SQL - Translator

> When we conduct index-based similarity search (with hint /*+indexnl*/ ~=)
> based on the results derived from an index-based selection, the index-based
> search does not work with a compilation error - {color:#de350b}ASX1030: The
> subtree does not have any data source{color}.
> Schema:
> {code:java}
> DROP dataverse test IF EXISTS;
> CREATE dataverse test;
> USE test;
> DROP DATASET lefttable IF EXISTS;
> DROP TYPE lefttype IF EXISTS;
> CREATE TYPE lefttype AS OPEN {
> leftid: string,
> leftname: string
> };
> CREATE DATASET lefttable(lefttype) PRIMARY KEY leftid;
> CREATE INDEX leftnameidx on lefttable(leftname) TYPE btree;
> DROP DATASET righttable IF EXISTS;

> };
> CREATE DATASET righttable(righttype) PRIMARY KEY rightid;
> CREATE INDEX rightleftidsidx on righttable(leftids) TYPE keyword;
> {code}
> Query:
> {code:java}
> USE test;
> SET `simthreshold` `0.0f`;
> SELECT LT.leftid, RT.rightid

> AND `word-tokens`(LT.leftid) /+indexnl/ ~= `word-tokens`(RT.leftids)
> ORDER BY LT.leftid, RT.rightid;
