Apache Spark is a fast, scalable data processing engine for big data analytics. In some cases, it can be 100x faster than Hadoop. Ease of use is one of the primary benefits, and Spark lets you write queries in Java, Scala, Python, R, SQL, and now .NET. The simple_query_string query supports multi-terms synonym expansion with the synonym_graph token filter. When this filter is used, the parser creates a phrase query for each multi-terms synonyms.
