API hangs when trying to return many fields #42
Description
Hi -
I'm the maintainer of the R package called patentsview, which provides an R client to the PatentsView API. I noticed some unexpected behavior where the API isn't responding to requests when the user is asking for many fields, especially when it comes to non-patents endpoints. This behavior is not deterministic, meaning sometimes I can get all the fields associated with the patents endpoint in a reasonable time frame, while other times I can't (though note I haven't been able to get all fields associated with the assignees endpoint at all, at least recently):
library(patentsview)
library(httr)
# timeout http request after 2 minutes
set_config(timeout(120), override = TRUE)
query <- "{\"patent_number\":\"5116621\"}"
# patents endpoint sometimes returns the complete set of fields in a timely fashion:
all_patents_fields <- get_fields("patents")
# fields being requested:

#> Error in curl::curl_fetch_memory(url, handle = handle): Timeout was reached: Operation timed out after 120004 milliseconds with 0 bytes receivedCreated on 2019-09-19 by the reprex package (v0.2.0.9000).
few notes:
- I've had
search_pv()print out the URL that it's requesting in the examples above, in case that's easier for you to debug. I know there are a lot of fields in the URLs and hence the example isn't exactly minimal/targeted, but I'm not sure what more I can do to hone in on what the issue actually is. - Previously the examples shown above were able to run in a reasonable time frame. It's been like 6-12 months since I last worked on the patentsview package, but the API was returning results for all fields (across all endpoints) pretty quickly at that time, say within 10 seconds for each request.
search_pv()gets the set of retrievable fields for a given endpoint by scrapping the fields from your webpage (e.g., the patents endpoint field list here: http://www.patentsview.org/api/patent.html). I don't think it's a matter of the wrong fields being requested, as sometimes a request will work for a given set of fields and other times it will hang indefinitely (at least for the patents endpoint...Recently I haven't been able to get all fields for the assignees endpoint).
