Specifying a boolean calculated field that will be 'true' if id is in the specified set

Question

I'm trying to add a boolean calculated field to a Solr request which will be true if the id field of the document is in the specified list of ids.

I'm trying to do it this way

fl=*,score,myfield:if(or(not(sub(id,1)),not(sub(id,2)),not(sub(id,3))),true,false)

But getting

Have I taken an entirely wrong approach (besides that I can do this outside Solr) or if this is how one would do it what should I change to make it work?

Answer 1

this should work (use more or() to add more id values):

&fl=*,score,myfield:or(exists(query({!v='id:1'})),exists(query({!v='id:2'})))

what is failing for you is probably that id is not a numeric type in schema so you cannot use sub(). So you could still try your way but id should be tint type for instance.
