Search filters do not support the | operator

[trangdata]

It seems that OpenAlex recently changed their API, and an example in our readme no longer works, which is a bummer — I was really enjoying using OR in search. There must be a reason behind this rationale. To be investigated.

library(openalexR)

works_search <- oa_fetch(
  entity = "works",
  title.search = c("bibliometric analysis", "science mapping"),
  cited_by_count = ">50",
  from_publication_date = "2020-01-01",
  to_publication_date = "2021-12-31",
  sort = "cited_by_count:desc",
  verbose = TRUE
)
