Issues retrieved with search_issues() has no .fields.comment

[egeland]

Describe the bug
If you retrieve a list of issues with JIRA.search_issues(), no comments are associated with the individual Issues in the list. You need to then use use JIRA.issue(id=<issue key>) to get a full Issue with comments.
It seems like "everything else" is included in the search results version of the Issue, so this feels like a bug.

To Reproduce
Steps to reproduce the behaviour:

api = JIRA(server=os.environ["JIRA_SERVER"], basic_auth=(os.environ["JIRA_USER"], os.environ["JIRA_PASS"]))
incomplete_issue = api.search_issues('project = "TEST" AND summary ~ "example"', maxResults=1)[0]

# The incomplete_issue has no comment field:
print(incomplete_issue.fields.comment)
# AttributeError: type object 'PropertyHolder' has no attribute 'comment'

# The full issue does have it:
full_issue = api.issue(id=incomplete_issue.key)
print(full_issue.fields.comment)
# <class 'jira.resources.PropertyHolder'>

Expected behaviour
The Issue retrieved with a search_issues() should be the whole Issue, not require another trip to the server.
or
The documentation should be very clear and explicit about this, which it is not at present time.

Set fields for search_issues is a workaround, but you have to set other fields as well.
issues = jira.search_issues(query, fields='comment,reporter', expand="changelog", maxResults=max_result)

You can also pass comments in the expand parameter as well.
I believe this is due to the comments being stored on a different table and keeping the request size small. However when you do it this way, you don't receive all the fields.
issues = jira.search_issues(query,expand="comments", maxResults=max_result)

I am also seeing the same behavior as egeland. Unfortunately specifying which fields to grab with the fields= parameter is not sufficient as I want to grab all fields.
