The Repeating Group element has the following properties in the What to search for section:

​
Basic properties

  • Each instance within one page. If you enable this option, the program will search for one instance of a repeating group on each page of a multi-page document. If instances of a repeating group can be located on a single page, do not enable this option.
  • Exclude previous instances. The following constraint is imposed on the instances of an element: no two instances may intersect. This is achieved by forcibly excluding the already detected instances.
  • Repetitions. Specifies the minimum and maximum number of instances on a page.
  • Min. no. of found subelements. Specifies the minimum number of group subelements that need to be detected in order for the group element as a whole to be considered detected.

​
Instances

The Instances section controls how the program locates subsequent instances of the repeating group relative to previously detected instances. These properties define the spatial relationship and distance constraints used when searching for the next instance.
  • Next instance. Specifies the expected position of the next instance relative to the previous one. Select a value from the drop-down list (for example, “Below Previous”) to indicate the direction in which the program should search for subsequent instances.
  • Up from the previous one. Specifies the maximum distance (in pixels) to search above the previous instance’s position when locating the next instance. This defines the upper boundary of the search area relative to the previous instance.
  • Down from the previous one. Specifies the maximum distance (in pixels) to search below the previous instance’s position when locating the next instance. This defines the lower boundary of the search area relative to the previous instance.
Setting Down from the previous one to a non-zero value restricts the search area for the next instance to the specified distance below the previous one. If line items are spaced inconsistently, this may cause instances to be missed. Set the value to 0 or leave it blank to remove the downward distance constraint.
If your extraction is not detecting all line items, check the Instances settings. Overly restrictive distance values are a common cause of missed instances, particularly after migrating skills to a new version of Vantage.
