General rule: - Use source filtering unless you can't. Source filtering works if the field is in the document you indexed. Fields is required if you want to load a stored field. You only _need_ to store fields if they are synthetic like from word count or from transform. Advanced thing I've never used: - Its possible to get some performance gains by setting a small field to stored and fetching it using fields rather than source filtering if the document is large and the field is small and you only want the small field.

I don't think we can deprecate fields because of synthetic fields (otherwise you could not eg. highlight them). But it's true that we'd like to make it unnecessary for you to store a field if you already have it in the \_source. Today `_source` filtering has the drawback that you might need to parse a lot of json to get a single value, this is a reason why users sometimes prefer storing some fields on their own so that they can be retrieved without parsing the \_source. We are thinking about ways to mitigate this issue, see eg. > > > Today we store the \`\_source\` is a single big binary stored field. While this is …great for simplicity, this also has the bad side-effect to encourage to store fields individually in order to save some json parsing when there are a couple of large field values and we are only interested in some short values. Maybe we could try to be a bit smarter and store the \`\_source\` across several stored fields so that it would not be an issue anymore? > > Random idea: given a document that looks like: > > \`\`\` json > { > "title": "short\_string", > "body": "very\_very\_very\_very\_long\_string", > "array": \[2, 3, 10\], > "foo": { > "foo": 42, > "bar": "baz" > } > } > \`\`\` > > we could for instance store all the top-level fields into their own stored field > > | Field | Values | > | --- | --- | > | title | "short\_string" | > | body | "very\_very\_very\_very\_long\_string" | > | array | \[2, 3, 10\] | > | foo | {"foo": 42, "bar": "baz"} | > > or maybe even each value individually (but it becomes more complicated with arrays of objects): > > | Field | Values | > | --- | --- | > | title | "short\_string" | > | body | "very\_very\_very\_very\_long\_string" | > | array | \[2, 3, 10\] | > | foo.foo | 42 | > | foo.bar | "baz" | > > Then we would have to make \`\_source\` filtering aware of the way fields are stored, and for instance if we store only top-level fields into their own stored field then we could translate an include rule like \`foo.\*\` to "retrieve field \`foo\`", and \`foo.bar.\*\` to "get everything under \`bar\` for field \`foo\`". -- Adrien Grand -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
