[jira] [Created] (SPARK-25232) Support Full-Text Search in Spark SQL

Lijie Xu created SPARK-25232:
--------------------------------

             Summary: Support Full-Text Search in Spark SQL
                 Key: SPARK-25232
                 URL: https://issues.apache.org/jira/browse/SPARK-25232
             Project: Spark
          Issue Type: New Feature
          Components: SQL
    Affects Versions: 2.3.1
            Reporter: Lijie Xu


Full-text search (i.e., keyword search) is widely used in search engines and relational databases like MATCH() ... AGAINST operator in MySQL. However, it is not natively supported in Spark SQL. We propose an approach to implement this full-text search in Spark SQL.

Our proposed approach is detailed  at https://github.com/JerryLead/Misc/blob/master/FullTextSearch/Full-text-issue-2018.pdf

and the prototype is available at https://github.com/bigdata-iscas/SparkFullTextQuery/tree/like_explorer
