Liang-Chi Hsieh commented on SPARK-25232:
-----------------------------------------
This looks to me more like a specific datasource that can support full text
search, e.g., Lucene or Elasticsearch. I think this can be a spark package
instead.
> 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
> Priority: Major
>
> Full-text search (i.e., keyword search) is widely used in search engines and
> relational databases such as MATCH() ... AGAINST operator in MySQL
> (https://dev.mysql.com/doc/en/fulltext-search.html), Text query in Oracle
> (https://docs.oracle.com/cd/B28359_01/text.111/b28303/query.htm#g1016054),
> and text search in PostgreSQL
> (https://www.postgresql.org/docs/9.5/static/textsearch.html). 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]
