How do I get the full content of a Splunk search result when using the Python SDK?

I can get the results from a one_shot query, but I can't get the full content of the _raw field.

import splunklib.client as client
import splunklib.results as results

def splunk_oneshot(search_string, **CARGS):
    # Run a oneshot search and display the results using the results reader

    service = client.connect(**CARGS)
    oneshotsearch_results = service.jobs.oneshot(search_string)

    # Get the results and display them using the ResultsReader
    reader = results.ResultsReader(oneshotsearch_results)
    for item in reader:
        for key in item.keys():
            print(key, len(item[key]), item[key])

This gives me the following for _raw:

('_raw', 120, '2013-05-03 22:17:18,497+0000 [SWF Activity  attNsgActivitiesTaskList1 19] INFO  c.s.r.h.s.a.n.AttNsgSmsRequestAdapter - ')

So this content is truncated at 120 characters. I need the entire value of the search result, because I need to run some string comparisons thereupon. I have not found any documentation on the ResultsReader fields or their size restrictions.

My best guess is that is caused by the insertion of special tags in the event raw data to highlight matched search terms in the Splunk UI front-end. In all likelihood, your search string specifies a matching literal term present in the raw data right at the point of truncation. This is not an appropriate default behavior for the SDK result-fetching method and there is currently a bug opened to fix this (internal reference DVPL-1519).

Fortunately, avoiding this problem is fairly trivial: One simply needs to pass segmentation='none' as an argument to the job.results() method:

(...)
oneshotsearch_results = service.jobs.oneshot(search_string,segmentation='none')
(...)

Do note that the 'segmentation' argument for the service.jobs() method is only available on Splunk 5.0 and onwards.
