Date filed	Issue number	Description

2019-12-17	MLA-3701	Search bars in Assistants will not display more than approximately 500k rows Workaround: This is mostly a visual issue - the actual number of results the Assistant will use when fitting a model is not affected.
2019-12-11	MLA-3686	MLTK Assistants do not support quote characters in field names Workaround: Use the "rename" or "eval" command to rename the field prior to using it.

2019-07-12	MLA-3237	Anova table does not allow some special characters in formula so in field names also Workaround: Rename your field names before running "score anova" if they include one or more of those special characters:  (r'[&%$#@!`\|";<>^]')
2019-03-28	MLA-2965	"Edit Job Settings" does not work in Assistants
2018-09-24	MLA-2547	Experiments can't be renamed until they have been filled and saved Workaround: Load the Experiment, fill all necessary fields, and save it. You'll be able to rename the Experiment in the Save dialog.

2018-04-18	MLA-2147	search.log does not show tracebacks on Windows on Splunk 7.1 Workaround: The user can still look at the logs on windows in mlspl.log which captures the traceback.

If this is the case, they will need to ask their Splunk administrators for access to this index.
