exlasticsearch v1.5.0 ExlasticSearch View Source
A collection of elasticsearch dsl’s to make development simple. The usage is meant to pair with existing ecto schema, like so:
defmodule MySchema do
...
use ExlasticSearch.Model
indexes :my_index do
settings Application.get_env(:some, :settings)
mapping :field
mapping :other_field, type: :keyword # ecto derived defaults can be overridden
end
end
You can then construct queries like so:
MySchema.search_query()
|> must(math(field, value))
|> should(match_phrash(field, value, opts))
|> filter(term(filter_field, value))
A repo model like ecto is provided, so a with ability to do most restful operations on records, in addition to calling search apis with the query structs above.
If additional data needs to be fetched or formatted prior to insertion into elastic, the ExlasticSearch.Indexable
protocol can be implemented to do that for you. A default implementation can also be generated as part of using
the ExlasticSearch.Model
macro.
