Sample 2. Step 6: Create a document identifier

Create a document identifier in FlexiLayout Studio by describing the form heading as a required Static Text element with search text and error tolerance.

When processing semi-structured documents in ABBYY FlexiCapture, you typically 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.

In this case, the document heading makes a good identifier element, because it contains distinct text that the OCR engine can read easily.

An identifier element or set of elements can be described in a predefined Header element (not used in this sample).

The document heading only identifies the document as belonging to this type. It is not recognized in ABBYY FlexiCapture.

In the FlexiLayout, describe 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

   Select SearchElements in the FlexiLayout tree.

3. Add a Static Text element

   Select the Static Text command in FlexiLayout → Add Elements → Static Text or in the shortcut menu of the element.

4. Name the element

   In the Name field, type a name for the element, for example, FormHeader.

5. Mark the element as required

   Select Required element on the General tab, because the document heading is a required element.

   
6. Open the Static Text tab

   Click the Static Text tab.

   
7. Enter the search text

   In the Search text field, type the text to find.

   The batch contains test documents with different headings: Easiest Recipes or Easy to Cook Recipes. Enter both headings.

   The headings appear on one line on all the test images. Type them without spaces to speed up the search for single-line static text, and separate the two alternative headings with |.

8. Set the maximum error percentage

   Set the maximum number of errors that the detected text may contain, in percentage points or as a number. In this case, set the Max error percentage to 20, which allows 5 errors among the 25 characters of the document heading.

   Set this maximum by trial and error.
