In the list below, the names of required properties appear in bold. Any other properties (not in bold) are considered optional. The table also indicates any default values, and whether a property supports the NiFi Expression Language.

Display Name	API Name	Default Value	Allowable Values	Description
Query Definition Style	el-rest-query-definition-style	FULL_QUERY	FULL_QUERY BUILD_QUERY	How the JSON Query will be defined for use by the processor.
Query	el-rest-query			A query in JSON syntax, not Lucene syntax. Ex: {"query":{"match":{"somefield":"somevalue"}}}. If this parameter is not set, the query will be read from the flowfile content. If the query (property and flowfile content) is empty, a default empty JSON Object will be used, which will result in a "match_all" query in Elasticsearch. Supports Expression Language: true (will be evaluated using flow file attributes and Environment variables) This Property is only considered if the [Query Definition Style] Property has a value of "FULL_QUERY".
Query Clause	el-rest-query-clause			A "query" clause in JSON syntax, not Lucene syntax. Ex: {"match":{"somefield":"somevalue"}}. If the query is empty, a default JSON Object will be used, which will result in a "match_all" query in Elasticsearch. Supports Expression Language: true (will be evaluated using flow file attributes and Environment variables) This Property is only considered if the [Query Definition Style] Property has a value of "BUILD_QUERY".
Query Attribute	el-query-attribute			If set, the executed query will be set on each result flowfile in the specified attribute. Supports Expression Language: true (will be evaluated using flow file attributes and Environment variables)
Index	el-rest-fetch-index			The name of the index to use. Supports Expression Language: true (will be evaluated using flow file attributes and Environment variables)
Type	el-rest-type			The type of this document (used by Elasticsearch for indexing and searching). Supports Expression Language: true (will be evaluated using flow file attributes and Environment variables)
