@martin I would go for valueType=lightning, reflects more the namespace.
@dave how would you address the "have any type of value" query?

@dellagustin @martin Open to anything on that front. Maybe valueType=* ?

@dellagustin @martin Or valueType=any?

@dave @dellagustin I like the name "valueType" - Would "any" not just be the same as omitting it? (I guess it's fine enough to have a default value for it)

@martin @dellagustin Omitting the parameter altogether, or do you mean just leaving it blank, like "valueType="?

@dave @dellagustin I meant omitting the parameter all together. I am unsure if there is a "standard" for "all" or "any" in web-apis, I think I have always gone with "all" myself, but I think that's more habit than anything else.

@martin @dellagustin Omitting it altogether would be a normal search that includes everything in the index. I think valueType=all would be good. That would give you only feeds that have some sort of value block attached, but without limiting it to lightning or hive, etc.

@dave @dellagustin Ah yes, logical fallacy there for me. I agree that "all" should return all feeds that have a value block no matter the "method". However, then I think it would make sense in the result to indicate what kind of monetization/payment type it supports (can it be multiple?).

@martin @dellagustin Good call on that.

@dave @martin @dellagustin is lightning explicitly mentioned in the rss value block? I seem to remember only seeing keysend

@brianoflondon @martin @dellagustin It's specified as a possible "type" in the <podcast:value> element. I don't think there is any language around it though.

@dave @martin I'm find with either, I think =any is my favorite.
