By default, BIC compares the recognition results and form identifiers using an error-tolerant algorithm.

1. On the Forms Classify tab, select the required row.
2. Click the Advanced Settings button.
3. In the Advanced Settings dialog box, complete the following substeps.
   1. Optional. In the Compare Text field, modify the string.
      Note: This might be necessary depending on the selected comparison method.
   2. From the Compare Method list, select one of the methods.
      Note: For more information, see Compare Methods.
4. If you want to assign several forms with similar identifiers or several versions of the same form to the same class, it may be useful to ignore leading or trailing characters of the recognition string. Complete any of the following substeps.
   • In the Ignore first characters box, enter a number or click an arrow.
   • In the Ignore last characters box, enter a number or click an arrow.
5. To perform the comparison neglecting leading or trailing characters of the comparison string, in the Max. compare distance box, enter a value or click an arrow. The compare distance computes as follows. Compare Distance = 1.00 - Number of Characters (Recognition String) / Number of Characters (Comparison String).
   Note: A match requires that the actual compare distance is less or equal the maximum compare distance.
6. In some cases, you may need multiple reading zones to obtain a reliable classification. In this case, you need to specify how the classification result is evaluated. To set the number of zones that must match, complete one of the following substeps.
   • On the Forms Classify tab, select Match all zones.
   • On the Forms Classify tab, clear Match all zones and then, to specify the number of required zones, in the Required number of box, enter a value or click an arrow.
