Issue Summary

When searching with a custom field that doesn't have a search template (search template is set to none) with JQL, we get the following error message.

Field '<customfield_name>' is not searchable, it is only sortable.

This error message is misleading as it suggests that the custom field is sortable. However, a custom field that is lacking a search handler, is neither searchable nor sortable.

So, trying to sort by the custom field also throws an error.

An unknown error occurred while trying to perform a search.

Steps to Reproduce

1. Create a custom field [ Gear > Issues > Custom Fields ]
2. Click the ellipsis button (...) on the newly create custom field and click "Edit Details"
3. Select "None" in Search Template.
4. Try searching using the custom field. Example JQL <Custom_field Name> IS NOT EMPTY
5. Also try sorting by the custom field.
   1. using JQL. example: ORDER BY <Custom_field name>

      Field '<customfield_name>' is not searchable, it is only sortable.
      

   2. Or, add the custom field as a column in issue search, then click the column header

      An unknown error occurred while trying to perform a search.
      

Expected Results

Since a custom field that is lacking a search handler, is neither searchable nor sortable, the error message should clarify that.

Actual Results

Field '<customfield_name>' is not searchable, it is only sortable.

The error message suggests that the custom field is sortable.

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
