Summary
The Search button in Issues > Manage filters > Search Filters appears to have no effect when clicked, displaying no result at all (not even the normal Your search criteria did not match any filters message when a search fails to find any filters):
Environment
Jira Data Center or Server using a Proxying Atlassian Server applications.
Diagnosis
This problem does not generate any log entries either in the JavaScript console or the Jira application log. However, if the Jira HTTP dump log is enabled then request parameters similar to the following will be observed, with what appear to be duplicate search parameter keys:
1
2
3
4
Request URL Parameters :
search=search
[...]
search=SearchBypass a proxy or SSL to test network connectivity for Jira Server and Data Center causes the search to function normally.
Cause
Jira's filter search uses two distinct query parameters, search=search and Search=Search. They are case-sensitive and both are required for the search to function correctly.
Some reverse proxies may normalise the query parameter keys, converting Search=Search into search=Search. This causes the search to fail.
Solution
Change the reverse proxy configuration not to modify query parameter keys.
