When I enter anything in the search bar and run it elastic search breaks with following in elasticsearch.log:
Caused by: java.lang.IllegalArgumentException: Fielddata is disabled on text fields by default. Set fielddata=true on [sortable_id] 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.
Any idea how to fix it? without working search wiki is useless.
