I'd like not to use analysis across my schema to save a bit of CPU (I know the penalty this inflicts on searching). Right now I set "index": "not\_analyzed" per field but this is cumbersome. I know I can choose between default analyzers [http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/analysis-analyzers.html](http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/analysis-analyzers.html)but there's no "none" analyzer to choose from. Short of writing a custom one that does nothing, is there a way to globally disable analysis? Eran -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

It feels like you're almost defeating the whole purpose of using Elasticsearch with this approach! Is it really that much of a problem?

We use ElasticSearch to index our structured analytics data. We chose it for a few reasons: 1. All fields are indexed so we can search by any field or combination of fields, including nested fields 2. Flexible and built in geospatial searches 3. Can scale with our data, which grows at ~100M documents a day It's pretty much a generic datastore (though not the source of truth). While we do have quite a few string fields in our data, these are mostly enumeration values ("connected", "not connected") and in preliminary tests we've found that disabling analysis (per field) shows savings of ~5% CPU. Not a huge amount but every bit helps. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

The "keyword" analyzer is the "none" analyzer you are looking for.

Ok that makes a bit more sense, but it seems the amount of CPU you will save isn't worth the effort. You could create an index template that matches fields with pattern "\*" and sets index: not\_analyzed, that'd be easiest.
