I've tried doing this in my Attachment class (doesn't work):
[String(Name = "_content", TermVector = TermVectorOption.WithPositionsOffsets, Store = true, Analyzer = "autocomplete"]
public string Content { get; set; }
I want to be able to specify an edgeNGram analyzer for the "_content" field so that I can perform autocomplete in my search for all mapper attachments. How can I achieve this?
My current index settings are as follows:
