Sample 1. Step 7: Create a form identifier

Identify documents in Sample 1 by adding a required Static Text element, IDHeader, that finds the HALLOWEEN REGISTRATION FORM document heading.

When you process semi-structured documents in ABBYY FlexiCapture, you often need to exclude documents that do not belong to the current type. One way to identify a document is to mark at least one element as required.

FlexiLayout Studio must detect a required element on every document of a given type. Otherwise, it cannot match the document to its FlexiLayout.

The document heading, HALLOWEEN REGISTRATION FORM, makes a good identifier element. It contains distinct text that the OCR engine reads easily.

You can also specify an identifier element, or a set of elements, in a predefined compound Header element, which this tutorial does not describe.

Use the document heading solely to identify the document as belonging to this type. In the FlexiLayout, specify the document heading as a Static Text element.

1. Open the FlexiLayout tab

   Click the FlexiLayout tab in the FlexiLayout Studio main window.

2. Select the SearchElements node

   In the FlexiLayout tree, select SearchElements.

3. Add a Static Text element

   Select FlexiLayout → Add element → Static Text, or right-click the element and select New → Static Text on the shortcut menu.

   In the Name field, type a name such as IDHeader.

4. Make the element required

   On the General tab, select Required element so the document heading is a required element.

   
5. Open the Static Text tab

   Click the Static Text tab.

   
6. Enter the search text

   In the Search text field, type the text to find: HALLOWEEN REGISTRATION FORM.

   Judging by the first image in the batch, the document heading fits on one line. You can type the heading without spaces to speed up the search for single-line static text.

7. Set the maximum error percentage

   Set the maximum number of errors allowed in the found text, either as a percentage or as a number. Set Max error percentage to 20, which allows 5 errors for the 25 characters of the document heading.

   You can find the optimal percentage of allowed errors only by trial and error.
