We are running into a situation where we need to access the iFilter text from within Workflow the same way you can access the OCR text results from within Workflow. Unfortunately, the two forms of text appear to behave differently.
In our tests, we have confirmed that we are getting iFilter text because we can do a text search through the client and get the pdf in the result set.
But when we use the Retrieve Document Text task in Workflow (V 9.2.1), we get an error, "Document has no Pages." unless we have also generated pages. (We no longer want to generate pages due to throughput reasons.) When we generate pages on our test pdf, Workflow does get these results - i.e. the OCR results.
So the question is, should Workflow be able to access the iFilter results? If this is not a native capability (hint, hint, maybe it should be) is the only alternative an SDK script?
