Description of Issue

when carrying out a search from any of the remote devices, iPhone, iPad or iMac for John Coltrane or Coltrane I get the error - cannot connect to roon search try again
if i try any other search, eg miles davis, elton john, john scofield the correct results are given.
The strange part is that if i simply search for john the first search returned is john coltrane.
I have restarted roon server and rebooted the NUC, but still get the same results. I have attached some screen shots for reference, can you please advise what the issue with search could be.

Thanks, Ian

If it is of any help, and for reference, here is what I get. Roon Server is on a Mac mini 2018, searching from Roon Remote on iPad:

[Ian_Watt (Ian)]

did a bit more digging and found that a search for john col was successful but a search for john colt would fail. I have added snapshots to show the result. I also checked the colts and you can see the fails starting during the search when the name search reaches john colt

This is an extract from the log and you can see where the search starts to fail when the search phrase reached john colt

Any ideas?
Thanks, Ian

Just updated the core and remote to the latest released build (2.0 (build 1357) and carried out the same search. Unfortunately the latest build does not resolve the problem and the search still reports that it can’t connect to Roon search.

Hi @Ian_Watt,

Thank you for the report. We’re investigating with development and will respond here once we have a clearer idea of what’s causing this behavior for you.

[Ian_Watt (Ian)]

Thanks Connor, I look forward to the findings and any updates the team may have.

[Ian_Watt (Ian)]

Hi, not sure if anyone else has noticed any change but I tried the search again today and it now seems to be working. A simple search for John Coltrane now returns the correct results and no longer fails to to connect to Roon search.
Although the report had not been updated with a fix this other report prompted me to try.
