For a Map/Reduce script I'm writing, I'm passing a search to map() that has multiple SUM(formulanumeric) columns, but the mapContext object only shows one of those columns as a result. It seems to ignore the others. Is there a trick to make it pick up each column?

The name of the column only needs to begin with formulanumeric, you can add on things like formulanumeric_abc to make it unique

Legend! Thanks for that. I couldn't find anywhere in the docs that mentioned I could do that, it just said I must put formulanumeric in the name. Awesome
