Method Description: Used on formula and non-formula (standard) fields. Returns the value of a specified search result column. For convenience, this method takes a single search.Column Object. This method is overloaded. You can also use Result.getValue(options) to get column values based on the name, join, and summary values for a column.
Returns: The return type depends on the type of search result column that was specified: boolean if the column is a check box field number if the column is a record, list, decimal number, or image field, with the following considerations: For image fields, the returned number represents the ID of the image file. string for all other column types, with the following considerations: For multiselect fields, the returned string represents a comma-separated list of IDs. Each ID represents a selectable option in the field. For date/time fields, the returned string represents the formatted string value of the date. You can use methods in the N/format module to work with this string (for example, converting it to a Date object). For more information, see N/format Module.
