Usage Notes

This function can only be used with Elasticsearch sources. At its simplest, the Lucene expression can be a list of words, such as CONTAINS( dremio sql). If no field names are specified, Dremio searches across all the fields in the document. To specify field names, use CONTAINS(<col1>:<search_term> AND <col2>:<search_term>).
