Right ;-)

I understand. After more thought, maybe it is not so bad that the
samples are indexed. Because the indexed terms are really shown there in
their context.

There were some spurious index terms as "p", "r", "for", probably
because of the samples, and they could be turned off as documented.

Then there are spurious terms as "point_type" because in the example I
often typedef a point a "point_type", but that term also exists as a
regular, indexable, entry. They have either to be turned off manually,
or turned on in specific sections, or I've to rename them to e.g. ptype
in the examples (which might actually be better).

But turning them off for specific sections does not work for me,
probably I do something wrong. I define:

point_type "" "(?!geometry.reference.adapted.register.*).*"

to omit it from all sections starting with reference.adapted.register,
but the point_type still appears there. I copied and pasted it from the
doc. I added !debug regular-expression , I don't see anything in the
log. I'm not a regex-expert and don't see what is wrong here.

Another question about this: is it possible to exclude a term twice? So e.g.

point_type "" "(?!geometry.reference.adapted.register.*).*"
point_type "" "(?!geometry.reference.exclude_also_from_this.*).*"

Or do I have to write a more complex regex for this?

Thanks, Barend
