Yah it seems to happen to me too (logging in and out didn't help), I was searching for [Cosmo Electronics KAQY214ATLD](https://lcsc.com/product-detail/Solid-State-Relays_COSMO_KAQY214ATLD_KAQY214ATLD_C136448.html) which was there few moments ago: I'm sure your brilliant team is already working on fixing this, thanks in advance for the fix! 😀 

Similar problem for me.  I picked the wrong weekend to design a new board it seems.

still I can't get any parts result but user contributed ones. :(

Yeah mine to, it usually works normally. But I found that changing the search engine (beside search bar) to "LCSC electronics" solve this, the search can find LCSC part number. Don't know if it is permanently changed or not.

Hi All We are investigating this issue now, we will try to fix it ASAP.
