Is it possible to define crawler Config Parameters in Fess properties?

English:Fess
1

If I want to use same crawler Config Parameter for every crawler, is there a way to define it in the Fess properties? Or elsewhere?

2

I think some parameters are available in fess_config.properties, it’s not all.

3

If I want to add new field in every crawler, e.g.
field.xpath.newlabel=(//SPAN[@class='label'])[1]
is it possibe to define it in fess_config.properties?

And thanks for quick reply again.

No, xpath is for only a config parameter.
