Non-latin Search on NodeBB

leksar

Hello.

I have a NodeBB v.0.7.0 running in Ubuntu 14.04.2 LTS. Database is on Redis 2:2.8.4-2..
I wish to have a search on my russian forum and Redis seems to be not working with non-latin symbols well.
So i installed Elasticsearch 0.90.7 on my server and nodebb-plugin-search-elasticsearch on NodeBB in hope it will solve the problem.
The only changes i made in Elasticsearch configs are two stings :

network.bind_host: localhost
cript.disable_dynamic: true

nodebb-plugin-search-elasricsearch settings you can see here
So the Dashboard indicates everything is OK, but when i'm pushing "Search" button the forum says "Oops ! Something went wrong !" and Elasticsearch stops.
./nodebb watch log
Elasticsearch logs spamming similar messages every minute

Any ideas i can get a workable russian search ?

Mm... yes for non-latin languages, dbsearch on redis doesn't work so well. Better on MongoDB.

Have you tried using the solr search plugin?

I'll try tommorow and report.

Looks like Solr works just fine. Thanks for solving my problem.

I actually just stumbled across it.

Seems to work for me. Wildcards aren't recognized, though. Don't know if that ever was the case.

The error is thrown by (line 18)

	escapeSpecialChars = function(s) {
		return s.replace(/([\+\-&\|!\(\)\{\}\[\]\^"~\*\?:\\\ ])/g, function(match) {
			return '\\' + match;
		});
	},

because the query string variable name in the payload seems to have changed from .query to .content. Thus s.replace fails, because s is of type undefined insted of the expected string.
