The search API is sometimes not returning records which I can find manually.
Example: https://permid.org/1-21537949617
The quote has these details:
- RIC: 2255.HK
- Ticker: 2255
- MIC: XHKG
However, both of these searches return "No Data Found":
- TICKER:2255 AND MIC:XHKG
- RIC:2255.HK


Another example which I can find by name but not identifiers is 0257.HK.
Some others which I can't find either by identifier or name are 1336.HK and 1919.HK (so I am not sure if the PermID doesn't exist or it is a search issue.)
Can you please assist? Thank you.
