I've added labels to some issues. I can log in and out of JIRA and open the Labels for the issues repeatedly, and the labels show up. But when I search for the labels I get no results. Why would this occur?
We have a self-hosted option with JIRA 6.2.3. The search seems to be failing for issues in the project I'm testing, but I have seen results returned for a general search across all projects, using labels I haven't personally added. Though when I use one of those labels in my project, I can't see that specific issue returned, even though other issues with the label in other projects are returned.
Are you using the labelText: (label) syntax? You can see more about searching here: https://confluence.atlassian.com/display/CONF50/Viewing+Labels+and+Labelled+Content
Hope this helps!
Sorry, Just realized this was for JIRA and not Confluence.
Are you using JQL - labels = "LabelName" and getting nothing back? If so, have you tried doing a re-index?
