TREX doesn't index some PDF documents ...
we have installed EP'04s and TREX ver. 7.00.42.00. It works well except one thing. TREX is not able to index some PDF documents. Most of them is indexed correctly but some documents not. Actually the problematic PDF documents are indexed but their content is not. In search result is displayed message "No document excerpt available" for the documents.
I found SAP Note 622419 that could relate with that but I don't know how can I check:
1. What encoding was used in particular PDF form.
2. What fonts or what font types were used in particular PDF form.
Do you have any idea how to find out these information about a document? Or do you know where could be problem when TREX are able to index content of just some PDF documents?
