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'
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:
