We had this exact same issue after we upgraded to V10 last month. Our Cath Lab coordinator couldn't find Durata leads which all have a slash in the mfg and vendor catalog number. I found that if I changed the slash to a dash they would appear and if I changed the dash back to a slash they would STILL be there. But the next day they were gone again. The only reason I could think of was that IC800 ran that night and reset the search criteria. I opened a case with Infor. This is what Keith Hill gave me.
There have been a few JTs entered for RQC searches. This particular one was entered as JT-900568. The resolution for this JT is in CTP113757 which is attached to KB 1873019. We are hopeful that no other related JTs will be required.
We've applied the patch to test and all seems to be working. Just waiting for our analyst to apply to production.
