Hello everyone, I am new in working with elasticsearch and found a behaviour which i didn't understand. If I create an index template with the type setting "\_source": { "enabled" : false} and the field mapping "doc\_values": false, the field with the deactivated doc\_values can still be queried. In my opinion, the information of the field is saved in the datatypes \_source and doc\_values. Is there another datatype where the Information is saved, too? Thank you for your help =) ---

So you are looking for not indexing a field, right? Set `index: no`. See [https://www.elastic.co/guide/en/elasticsearch/reference/current/mapping-index.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/mapping-index.html) ---

Thanks for the fast reply. But sadly i don't look for that. I study Elasticsearch for my Bachelor Thesis and want to look inside the architecture. I want to understand, why i can search for this field even though \_source and doc\_values is deactivated. Maybe there's something cached or another datatype in the Lucene Index deep in the architecture? ---

Yes. You can search in a field when the field is indexed. Which is the default behavior. ---

Do you mean indexed in the inverted Index ? I thought only strings will be stored in the inverted Index and digits (integers, longs) are not stored in this datatype. Am i wrong? ---

Not sure about what you mean. May be others can comment. But basically, if you need to: - search, you have to index the field (whatever his type) - compute aggregations, you need to have doc values - get the original field content (either store the field or get the content from the default `_source` field). ---

Okay, point 2 and 3 are absolutely clear for me. I understood, that we have in one shard (lucene index) three datatypes: - the inverted index (There are the terms of a string with the location and document, which contains this term) - the \_source (Here you can find the original JSON-Form of the document) - doc\_values (Original data of a document in a column-oriented fashion) And i thought that the inverted index is only for strings and not for the other types. Every example in the internet is without a integer or something else. See: [https://www.elastic.co/guide/en/elasticsearch/guide/current/inverted-index.html](https://www.elastic.co/guide/en/elasticsearch/guide/current/inverted-index.html) And the precise Question is now: When i deactivate \_source and doc\_values for a field with an integer (for instance the field "bytes"), is it also stored in the "inverted index"? If this is true, it makes sense that i can filter documents with a specific number of "bytes" without \_source and doc\_value. ---

Ahh okay =) Thanks a lot! 😉 That's not mentioned in the documentation of elastic, precisely. Thanks and have a nice day! =) ---
