Search Method

Search For Items Listed Below - This method selects wells from a list of the unique remarks in the selected data item.  This option is best used for text fields with a relatively small number of unique values, such as a source code or flag.  Text fields like comments, on the other hand, can have a totally unique entry for every well; the Keyword search is a much better option for text fields like this.
