In this directory you can see several complete examples demonstrating key
concepts and patterns exposed by elasticsearch-dsl.
The alias migration example shows a useful pattern where we use versioned
indices (test-blog-0, test-blog-1, ...) to manage schema changes and
hides that behind an alias so that the application doesn't have to be aware of
the versions and just refer to the test-blog alias for both read and write
operations.
For simplicity we use a timestamp as version in the index name.
More complex example highlighting the possible relationships available in elasticsearch - parent/child and nested.
A helper function using the composite aggregation to paginate over aggregation results.
A BlogPost document with automatic classification using the percolator
functionality.
As example using completion suggester to auto complete people's names.
