How to sort Norwegian special characters with the ICU plugin?

Olav_Gronas_Gjerde · July 23, 2013, 1:36pm

I have a problem sorting my searches correctly by using norwegian collation.

I've installed the
https://github.com/elasticsearch/elasticsearch-analysis-icu plugin, and
I've created my index with the following properties.

Java:
.startObject("analysis")
.startObject("analyzer")
.startObject("collation")
.field("tokenizer", "keyword")
.field("filter", "norwegianCollator")
.endObject()
.endObject()
.startObject("filter")
.startObject("norwegianCollator")
.field("type", "icu_collation")
.field("language", "norwegian")
.endObject()
.endObject()
.endObject()

JSON:
{
"index": {
"analysis": {
"analyzer": {
"collation": {
"tokenizer": "keyword",
"filter": "norwegianCollator"
}
},
"filter": {
"norwegianCollator": {
"type": "icu_collation",
"language": "nb"
}
}
}
}
}

Elasticsearch Head show this as:

settings: {

index.analysis.analyzer.default.filter: norwegianCollator
index.analysis.filter.norwegianCollator.type: icu_collation
index.analysis.analyzer.collation.tokenizer: keyword
index.analysis.filter.norwegianCollator.language: norwegian

}

Is this correctly configured?

For search I'm doing this:

    QueryBuilder qb = QueryBuilders.matchQuery(
            "customer.partner",
            "1"
    );
    SearchResponse response =
            this.esClient.prepareSearch(this.client.getName())
            .setTypes("customer")
            .setSearchType(SearchType.DFS_QUERY_THEN_FETCH)
            .setQuery(qb)
            .setFrom(0).setSize(size)
            .addSort("name", SortOrder.DESC)
            .execute()
            .actionGet();

But the result I get is:

DEBUG 15:21:00 search.ESSearch - {enabled=true, name=ølen fiskelag,
partner=1}
DEBUG 15:21:00 search.ESSearch - {enabled=true, name=æ vil ha dæ, partner=1}
DEBUG 15:21:00 search.ESSearch - {enabled=true, name=åges plateselskap as,
partner=1}
DEBUG 15:21:00 search.ESSearch - {enabled=true, name=yara international,
partner=1}

When it should be:

DEBUG 15:21:00 search.ESSearch - {enabled=true, name=åges plateselskap as,
partner=1}
DEBUG 15:21:00 search.ESSearch - {enabled=true, name=ølen fiskelag,
partner=1}
DEBUG 15:21:00 search.ESSearch - {enabled=true, name=æ vil ha dæ, partner=1}
DEBUG 15:21:00 search.ESSearch - {enabled=true, name=yara international,
partner=1}

What am I doing wrong? What could be missing in my configuration?

Hi,

just quickly looked at your code and I am not sure you are providing a
valid language code. As far as I understand you need to provide code
according to ISO 639-2 Language Code List - Codes for the representation of names of languages (Library of Congress)
(for norwegian
there are couple of options: no, nb, nn. I dunno what is he difference.)
Can you try it with "no" for example?

Also note that it might be more helpful if you can provide examples using
curl (see Elasticsearch Platform — Find real-time answers at scale | Elastic for details).

Regards,
Lukas

They are valid, 'nb' is Bokmål, and 'nn' is Nynorsk, both are official
norwegian languages.

You should try language code "nb" instead of "norwegian" in the Java
example.

I've tried nb, no and nn, sorting of the æ, ø ,å letters are still in wrong
order.

It works here, see this curl example Norwegian Bokmål sort with Elasticsearch · GitHub

Is the issue your Java code?

Thank you! That full example solved it! I had not added the "analyzer" :
"bokmalAnalyzer" part to my index property mapping. However that wasn't the
only thing, I had to remove the .field("index", "not_analyzed") property
setting

But now it works exactly as it should! Again, thank you for your help!
