I'm indexing documents with nested objects where some of the objects include unique ids (GUIDS). I want all such fields to be "not_analyzed." The id fields always have an '_id' suffix however, these fields can appear at arbitrary levels in the document hierarchy. I'm trying to come up with a dynamic mapping template to address this so that any field of the form "*_id" regardless of the nesting depth will be marked as "not_analyzed." I don't think there's a way to specify this as a single patch_match, but I just wanted to confirm that I'm not missing something. In practice, I suppose the nesting will never go deeper than let's say, 5. So I could define 5 path_match patterns like *_id, *.*_id, *.*.*_id...etc. Although experience shows that the moment I do this, we'll find the need to go to 6 levels ;-). Ideally, you'd be able to specify a path in ANT-like syntax e.g., **/*_id. Maybe I'll write up an enhancement request for this.
