[2018-11-29T12:31:03,568][DEBUG][o.e.a.s.TransportSearchAction] [82Ll0tA] All shards failed for phase: [query] org.elasticsearch.ElasticsearchException$1: Fielddata is disabled on text fields by default. Set fielddata=true on [system.process.name] in order to load fielddata in memory by uninverting the inverted index. Note that this can however use significant memory. Alternatively use a keyword field instead.
Need syntax for enabling fielddata and reindexing.
