Hi guys, Originally I posted this in SO but found this place which seems more suitable to ask 🙂 I have an elasticsearch index where my default analyzer is the snowball analyzer so I can get the stemming and now I need the ability to have synonyms on some of the fields as well as the benefit of the snowball analyzer to do stemming. Is this possible and if so how? As a test I tried to set a synonym filter on the snowball analiyzer, hoping that it would enable synonyms on all fields so I can test it but that didn't really work... I created another analyzer for synonyms on my index with the WordNet synonym file. If I am not clear please let me know and I'll try and update. Here is my current index settings. "settings": { "index": { "analysis": { "analyzer": { "synonym": { "filter": [ "synonym" ], "tokenizer": "whitespace" }, "default": { "language": "English", "type": "snowball" } }, "filter": { "synonym": { "type": "synonym", "synonyms\_path": "/elasticsearch/wn\_s.pl", "format": "wordnet" } } } } } } -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

You would need to create a custom analyzer by basically repeating the configuration of the snowball analyzer, but adding in the synonym filter. You can't modify a stock analyzer, unless this has changed (if so, someone please correct me). -- Ivan On Wed, Nov 5, 2014 at 6:43 PM, Iqbal Ahmed [iq.quit@gmail.com](mailto:iq.quit@gmail.com) wrote: > Hi guys, > > Originally I posted this in SO but found this place which seems more > suitable to ask 🙂 > > I have an elasticsearch index where my default analyzer is the snowball > analyzer so I can get the stemming and now I need the ability to have > synonyms on some of the fields as well as the benefit of the snowball > analyzer to do stemming. > > Is this possible and if so how? > > As a test I tried to set a synonym filter on the snowball analiyzer, > hoping that it would enable synonyms on all fields so I can test it but > that didn't really work... > > I created another analyzer for synonyms on my index with the WordNet > synonym file. > > If I am not clear please let me know and I'll try and update.
