Preparing an OCR Scan-Query

We provide a MetaClass "OCRSCANQUERY OCR Text scan queries" deriving from System.Query.QUERY. There is already one instance QRY_OCRSCANQUERY available in it but, we want to set up a new one so we will leave this one as it is.

1. Create a new instance of OCRSCANQUERY
2. Set the according filter object (FILTEROBJECT) similar as for other queries
3. Add this new query to the list of Infrastructure objects
4. Prepare and add a QUERYSCOPE to the ACM
5. Prepare and add a View Item to the view set in the Context of the ACM
   

Preparing the object

1. Ensuring the object can be found by the clients offline search we need to classify the object's MetaClass as SYSCLS OBJECTWITHOCRTEXT and implement the necessary properties
   
2. Enter the value of the OCRText in the property
