Hi Mikhail, Thank you for the definitive answer!
I could "solve" this by adding a header in the document with proper information to guide the indexing process. Header will be parsed then ignored by the tokenizer. However, the header along with the actual text will be stored together in that field... I wonder (again...) if it's possible I may control which part of the text shall be stored during the index process? In other words, is it possible to strip the header when storing the text into the field?

External Email - Use Caution Hello Guan. It reminds me https://youtu.be/EkkzSLstSAE?t=1531 timecode. I'm afraid it's quite far from the existing codebase where the Field has no reference to enclosing Document. sigh.
