7 months ago Wow this one is really really weird. The problem isn't even about length of the query string. Minimal reprex:
query_substr <- "https://api.openalex.org/works?page=1&filter=title_and_abstract.search:%22Agriculture+reform%22+OR+%22ocean+reform%22"
oa_request(query_substr)
#> Warning in oa_request(query_substr): No records found!

So instead of this url from above:
bad_url <- "https://api.openalex.org/works?page=1&filter=title_and_abstract.search%3A%22Agriculture%2Breform%22%2BOR%2B%22ocean%2Breform%22&per-page=1"GET() should instead be sending something like this:
good_url <- "https://api.openalex.org/works?page=1&filter=title_and_abstract.search:%5C%22Agriculture+reform%5C%22+OR+%5C%22ocean+reform%5C%22&per-page=1"

query_url2 <- gsub("%22", "%5C%22", query_url)This still errors though, but now for a different reason - it's just genuinely long:
cat(rawToChar(
httr::GET(query_url2)$content
))
#> <html>
#> <head>
#> <title>Bad Request</title>
#> </head>
#> <body>
#> <h1><p>Bad Request</p></h1>
#> Request Line is too large (4468 > 4094)
#> </body>
#> </html>Overall I'm completely stumped though. I have no idea why this is an issue and whether this is on our end, OA's end, httr's end, etc.
