Possibility to read out search filters using jira-python

Question

Is there another possibility to gather information about issue search contents as stated below?

My first attempt was:

for i in jira.search_issues('filter=filterID', startAt=0, maxResults=2500):
    print(i.fields.duedate)

The index i resembles the issue name (e.g. JIR-001). When counting i it returned exactly 1000. So I guess the plugin can't return more issues, but my JIRA has way more issues related to that filter ID (thats why I chose 2500). Is there a way to get more without adding another loop where the startAt and maxResults is shifted to the next 1000 results (startAt=1000, maxResults=1999)? Because this increases the runtime of the script dramatically, whereas a search.issue access eats up around 9 seconds.

Maybe there is a much easier way for that problem, but the documentation of the package is quite sparsely about that specific problem.

It may be interesting for you to check the source code of jira.search_issues() function.

Here is a source code for version 1.0.3:

def search_issues(self, jql_str, startAt=0, maxResults=50, validate_query=True, fields=None, expand=None,
                  json_result=None):
    """
    Get a ResultList of issue Resources matching a JQL search string.

    :param jql_str: the JQL search string to use
    :param startAt: index of the first issue to return
    :param maxResults: maximum number of issues to return. Total number of results
        is available in the ``total`` attribute of the returned ResultList.
        If maxResults evaluates as False, it will try to get all issues in batches of 50.
    :param fields: comma-separated string of issue fields to include in the results
    :param expand: extra information to fetch inside each resource
    """
    # TODO what to do about the expand, which isn't related to the issues?
    infinite = False
    maxi = 50
    idx = 0
    if fields is None:
        fields = []

    # If None is passed as parameter, this fetch all issues from the query
    if not maxResults:
        maxResults = maxi
        infinite = True

    search_params = {
        "jql": jql_str,
        "startAt": startAt,
        "maxResults": maxResults,
        "validateQuery": validate_query,
        "fields": fields,
        "expand": expand
    }
    if json_result:
        return self._get_json('search', params=search_params)

    resource = self._get_json('search', params=search_params)
    issues = [Issue(self._options, self._session, raw_issue_json)
              for raw_issue_json in resource['issues']]
    cnt = len(issues)
    total = resource['total']
    if infinite:
        while cnt == maxi:
            idx += maxi
            search_params["startAt"] = idx
            resource = self._get_json('search', params=search_params)
            issue_batch = [Issue(self._options, self._session, raw_issue_json) for raw_issue_json in
                           resource['issues']]
            issues.extend(issue_batch)
            cnt = len(issue_batch)
    return ResultList(issues, total)

It has an interesting comment:

Total number of results is available in the total attribute of the returned ResultList.

So you may want to check it.

You may also want to set maxResults = False

Documentation:

If maxResults evaluates as False, it will try to get all issues in batches.
