The method retrieveRecordsMatching() automatically unformats the retrieved records in the operation context. This method takes three arguments: the search condition string, the context instance, and either the output formatter instance or the output formatter name.
Each of the above retrieval methods returns, by default, every table column for each returned record. If fewer columns are required, an additional argument is used: a Vector with elements containing the names of the columns to be retrieved. The order in which the column names are entered into the Vector is not significant.
