Are the rate limits for web search - which is 200/day for IEEE - aggregate numbers for all jabref installation? i.e. if there are 201 people who just issue one search, then the last one will get an error? (Just trying to understand why IEEE search has not worked for me for months)
You are right! The 200 calls/day are for all JabRef users in total. We are in contact with IEEE to think of possible solutions.
The GitHub issue is IEEE Seach not working · Issue #6837 · JabRef/jabref · GitHub.
