Hey, I'm trying to get a trigram analyzer working but i'm fairly sure i'm doing something wrong because as i understand it it doesn't generate any terms at all for my document. I've done a complete log with curl commands of what i'm doing here: [https://gist.github.com/luuse/cb707b85c73f8e82cd8d](https://gist.github.com/luuse/cb707b85c73f8e82cd8d) 1. So i start with creating the index and at the same time i add the analyzer and a mapping for all fields in my document. The response when i create it is in create.json and the body i send is in mapping.json. 2. I index the document in url.json and get the response in index.json 3. I get the termvector in termvector.json 4. I query it with "jen" and the analyzer trigrams figuring it should match against "jenkins" but no results 5. I query it with "jen\*" and still the analyzer trigrams and get the jenkins result So I have two questions... a. When i fetch the termvector it looks like it empty. Is this correct? b. Have i missed some detail or what am i doing wrong? Why isn't it working? I can provide more details if you want. I'm running v1.2.1 in a docker container.

Hello, You are performing a search by uri, by default it searches in the \_all field. In your case this field doesn't use at all your trigrams analyzer. You could either pass an explicit query : {"query": {...} }, or specify which field you want to match: curl -XGET '[http://localhost:9200/urls/\_search?q=jen&analyzer=trigrams&pretty=true&df=title](http://localhost:9200/urls/_search?q=jen&analyzer=trigrams&pretty=true&df=title)' I think it works for "jen\*" because it's converted into a wildcard query. For the termvectors, you have to enable them in your mapping: > **[Elasticsearch Platform — Find real-time answers at scale](https://www.elastic.co)** > > Power insights and outcomes with the Elasticsearch Platform and AI.

I understand that my fields aren't in the \_all field and that's why my query fails. But shouldn't they be included in \_all by default according to the documentation, "index" defaults to "analyzed" and "include\_in\_all" default to "true"? > **[Elasticsearch Platform — Find real-time answers at scale](https://www.elastic.co)** > > Power insights and outcomes with the Elasticsearch Platform and AI.
