 When I wrote this that was a little over 200 000 SNPs. It's probably not a good idea to set `retmax` to 200 000 and just download all of those identifiers. Instead, we could store this list of IDs on the NCBI's server and refer to them in later calles to functions like `entrez_link` and `entrez_fetch` that accept a web history object.

 As you can see, the result of the search now includes a `web_history` object. We can use that object to refer to these IDs in later calls. Heree we will just fetch complete records of the first 5 SNPs.
