Bug: 'hot topics' feature should use terms, not significant_terms
The 'word cloud' option turns on the 'hot topics' under the statistics panel.
The topics are currently generated using the ES 'significant_terms' aggregation.
If the intention is to show the hot topics for the selected messages, then I think this is the wrong aggregation.
Significant_terms shows terms in the selection which occur more frequently relative to the average in the background - which in this case is the mbox index. I think it would make more sense to show the busiest terms for the selection only.
This would have the advantage that the aggregation will work on ES 5.x without needing to enable fielddata on the subject field.
The aggregation can also be filtered by providing exclusions, e.g. the following will exclude words or 3 letters or fewer:
"exclude": ".|..|..."
The exclusion list could be defined as a config item, with a suitable default (e.g. as above)

In fact the 'terms' aggregation also does not work on ES 5.x for text fields.
(The other aggregations are all done on keyword fields)
