I tried following JQL search that is working :
project = XXXX and type = YYYY and component = "[ART] toto"
but I would like to seach all issues that has component field that contains "toto" string.
for instance :
project = XXXX and type = YYYY and component ~ "toto"
but then I have this error :
"The operator '~' is not supported by the 'component' field."
what would be the solution to search issues with a field that has one string inside its different values ?
