Purpose:	Builds the IFetchDataRequest for the current
	ttEntitySearchQuery record
Notes:	The Fields option limits what the DataAccess layer reads to
	the columns that are actually returned to the caller

Returns	Consultingwerk.OERA.IFetchDataRequest
	The IFetchDataRequest for the current query

Top

Purpose:	Removes the rows already produced for the current
	ttEntitySearchQuery record
Notes:	A failed query must not return a partial result alongside its
	error message. Whether the rows created before the failure
	are rolled back by the enclosing block depends on whether a
	transaction is active, so they are removed explicitly here

Top

Purpose:	Executes the query of the current ttEntitySearchQuery record
	and creates its ttEntitySearchRow records
Notes:	Operates on the ttEntitySearchQuery record the caller is
	positioned on

Top

Purpose:	Returns the Fields of the current ttEntitySearchQuery record
	as the table.field list an IFetchDataRequest expects
Notes:

Returns	CHARACTER
	The comma-delimited list of table.field entries

Top

Purpose:	Executes every query of the dataset and returns the matching
	records as ttEntitySearchRow records
Notes:	The RowCount and ErrorMessage fields of a query record are
	filled by this method and travel back to the caller in the
	same dataset.
SCL-5983:	Published as the REST method
	POST /SmartFramework/Search/EntitySearch for the web command
	palette. The request body carries the dsEntitySearch dataset
	with the ttEntitySearchQuery records, the response returns the
	same dataset with the ttEntitySearchRow records nested below
	their query (data-relation drQueryRow on RequestId):
	- RowCount of a query is the number of rows returned for it,
	limited by MaxRows (0 = no limit)
	- A query that fails does not fail the request - its
	ErrorMessage is set, it returns no rows and the other
	queries still return their rows. This includes a query
	rejected by IRequestAuthorizationProvider:IsFetchDataRestricted,
	as every query is executed through ServiceInterface:FetchData
	- FieldValues holds the values of the FieldNames of the query,
	in that order, delimited by CHR(1) - in JSON that is the
	character \u0001 the client splits on

Parameters:
dsEntitySearch	DATASET dsEntitySearch
	INPUT-OUTPUT The dataset with the queries to execute
