Let's say you have an internal tessconfig file in the parser that you've configured through a tikaconfig. When, at runtime, you send in a new tessconfig via the parsecontext, how can we tell which parameters you want to change from the new tessconfig?
Yes, I realize that it would be possible to keep track of what parameters have been changed in the runtime config and then do something smart, but this hasn't been an issue to date.
