Functions

Builds a search query on top of the given query from the rummage parameters from the given rummage struct.

Examples

When rummage struct passed doesn’t have the key “search”, it simply returns the query itself:

iex> alias Rummage.Ecto.Hooks.Search
iex> import Ecto.Query
iex> Search.run(Parent, %{})
Parent

When the query passed is not just a struct:

iex> alias Rummage.Ecto.Hooks.Search
iex> import Ecto.Query
iex> query = from u in "parents"
#Ecto.Query<from p in "parents">
iex>  Search.run(query, %{})
#Ecto.Query<from p in "parents">

When rummage struct passed has the key “search”, with “field” and “term” it returns a searched version of the query passed in as the argument:

iex> alias Rummage.Ecto.Hooks.Search
iex> import Ecto.Query
iex> rummage = %{"search" => %{"field_1" => "field_!"}}
%{"search" => %{"field_1" => "field_!"}}
iex> query = from u in "parents"
#Ecto.Query<from p in "parents">
iex> Search.run(query, rummage)
#Ecto.Query<from p in "parents", where: like(p.field_1, ^"%field_!%")>
