CirrusSearch has to force the plain highlighter on array fields. Track upstream issue: https://github.com/elasticsearch/elasticsearch/issues/3757
This landed in Lucene a few days ago. Elasticsearch will get it for free when they update to Lucene 4.7. We'll get it after they release that....
On queries with a large handful of terms the plain highlighter starts to slow down significantly. On a search for "united states house of representatives elections in washington 2004" it took 300ms, about as long as the search and rescore phase combined.
Setting to high because it'll be worth improving performance.
