Override Fess properties values in crawler Config Parameters?

Is it possible to override Fess properties values in crawler Config Parameters,
for example crawler.document.html.content.xpath?

For crawler.document.html.content.xpath, you can set it as xpath.default.content in Config Parameters. Other parameters are here.

Thank you for quick reply.

Actually the setting xpath.default.content does not work. It has to be field.xpath.default.content.
The key must start with XPATH_PREFIX, which is “field.xpath.”:

Java 11 is now required for the Fess. Is it possible to update remote debug parameters?

field.xpath.default.content is correct.
To update debug parameters, please use jvmOptions.
