A rgbif user is asking me about a particular download query, see https://github.com/ropensci/rgbif/issues/245 

TLDR: AFAICT this can't work as the API is set up right now. Or am I wrong?  

That is, he wants to get data for records that match

- 10 taxa with their taxonKey value

- 3 different basisofrecord values

- country = US 

- hasCoordinate = TRUE

- hasGeospatialIssue = FALSE

- year range between 1949 and 2011

- month range between 3 and 8

For the taxonKey values, I think he needs to combine those with OR operator:

However, he should combine the other parameters (basisofrecord, hasCoordinate, year, month, etc) using AND AFAICT. 

BUT, AFAICT the API only allows one predicate key so you can't do what I think is needed here. That is, to say (taxonkey = 1 OR 2 OR 3) + (country = US AND hasCoordinate = true, etc.)

I tried sending two predicate keys in the API and only the second goes through. 

Any guidance much appreciated :)

The best solution I can think of is to do the query he's doing, but do one for each taxon. Seem like a good solution?

Best, Scott
