Hi,
is there any more efficient way to get the synonyms which are saved in a
synonym token filter than parsing the \_settings answer of an index?
The settings response look like this as json and I am only interested in
the actual synonym lines.
- index.analysis.filter.fbl\_synonym1\_filter.synonyms.2: test2, test3
- index.analysis.filter.fbl\_synonym1\_filter.synonyms.1: test1, test2
- index.analysis.filter.fbl\_synonym1\_filter.synonyms.0: -, \_
-
{
- fbl\_synonym1: {
- settings: {
- index.number\_of\_shards: 4
- index.number\_of\_replicas: 0
- index.analysis.filter.fbl\_synonym1\_filter.type: synonym
- index.analysis.filter.fbl\_synonym1\_filter.synonyms.2: test2,test3
- index.analysis.analyzer.fbl\_synonym1\_analyzer.type: custom
- index.analysis.analyzer.fbl\_synonym1\_analyzer.tokenizer:
lowercase
- index.analysis.filter.fbl\_synonym1\_filter.synonyms.1: test1,test2
- index.analysis.filter.fbl\_synonym1\_filter.synonyms.0: -, \_
- index.analysis.analyzer.fbl\_synonym1\_analyzer.filter:
fbl\_synonym1\_filter
- index.version.created: 900799
- index.uuid: 5cqvi4DcROmxiVf4axOi6g
}
}
}
A java api solution would be awesome.

The actual filter has no public accessor for the internal synonym map, so
it is not possible that way. However, you can simply look at its code and
figure out how it is reading the synonyms and replicate it:
[https://github.com/elasticsearch/elasticsearch/blob/master/src/main/java/org/elasticsearch/index/analysis/SynonymTokenFilterFactory.java#L57-L69](https://github.com/elasticsearch/elasticsearch/blob/master/src/main/java/org/elasticsearch/index/analysis/SynonymTokenFilterFactory.java#L57-L69)
The synonyms unit test does not use the yml file, but it is still a good
place to learn from:
[https://github.com/elasticsearch/elasticsearch/blob/master/src/test/java/org/elasticsearch/index/analysis/synonyms/SynonymsAnalysisTest.java](https://github.com/elasticsearch/elasticsearch/blob/master/src/test/java/org/elasticsearch/index/analysis/synonyms/SynonymsAnalysisTest.java)
Cheers,
Ivan
