This group has the following settings:

Maximum number of alternatives

This setting is available only when the Field type setting is set to Simple field.

Type or select a number to limit the number of alternatives returned by the Standard Evaluator, to produce a more manageable amount of data. This is generally used when only the first few results are important. (Default: 2)

The alternatives are first ordered according to the "Best of" or "First of" evaluation. This list is then shortened to the number of alternatives you specify using the Maximum number of alternatives setting.

If the highest alternatives all have equal confidence, this limit may prevent important data from being considered for the field result. The best practice is that you specify a limit of at least 2 so that the field is aware of any conflict between similar confidence alternatives.

Ignore empty alternatives

Select this setting if you want to ignore empty alternatives so they are not possible results for this evaluator. (Default: Cleared)

This setting is available only when the Field type setting is set to Simple field.

Minimum confidence

This setting is available only when the Field type setting is set to Simple field and the Evaluation type setting is set to First of.

Specify the number of rows by typing a number or using the arrow keys. (Default: 80)

Minimum number of rows

This setting is available only when the Field type setting is set to Table field and the Evaluation type setting is set to First of.
