Now that the feature of setting metadata in document level is available, I would further prefer setting metadata in chunk level, which would more helpful for retrieving chunks.
I have tried two alternative way.
The first is the table parsing method in which the columns other than the chunk text column play as the metadata, but it is not as well as expected.
Another is setting the tags to each chunk. It looks useful, but I have to set the tags to each chunk mannually, I don't know if there were more efficient way to set tags to chunks, API would be ideal.
Any suggesion would be appreciated.
