Algolia Search API Client for Erlang

Setup

Add to deps section in your rebar.config:

{algolia, ".*", {git, "git://github.com/k3nn7/algoliasearch-client-erlang.git", {tag, "0.1.0"}}}

And run:

$ rebar get-deps

This library uses ibrowse and ssl applications so start them first:

1> ibrowse:start().
{ok,<0.52.0>}
2> ssl:start().
ok

After that initialize client with you ApplicationID and API-Key:

Client = algolia:make_client("YourApplicationID", "YourAPIKey").

Quick Start

Use follow code to add object to example index:

1> Index = algolia:init_index(Client, "example").
2> Object = #{<<"content">> => <<"foo">>}.
3> algolia_index:add_object(Index, Object).
{ok, #{<<"createdAt">> => <<"2016-01-24T08:34:47.700Z">>,
  <<"objectID">> => <<"129196290">>,
  <<"taskID">> => 699175850}}

Now you can query this index:

4> algolia_index:search(Index, <<"foo">>).
{ok, #{<<"hits">> => [
    #{<<"_highlightResult">> => #{<<"content">> => #{<<"matchLevel">> => <<"full">>,
      <<"matchedWords">> => [<<"foo">>],
      <<"value">> => <<"<em>foo</em>">>}},
      <<"content">> => <<"foo">>,
      <<"objectID">> => <<"53383650">>}],
    <<"hitsPerPage">> => 20,
    <<"nbHits">> => 1,
    <<"nbPages">> => 1,
    <<"page">> => 0,
    <<"params">> => <<"query=foo">>,
    <<"processingTimeMS">> => 1,
    <<"query">> => <<"foo">>}}

Commands reference

It is just an overview of functions that this library provides. For more detailed description of parameters that you can use please see official Algolia REST API Reference.

Add new object to the index

Example with automatic objectID assignment:

1> Object = #{<<"content">> => <<"foo">>}.
2> algolia_index:add_object(Index, Object).

Add object with given objectID:

1> Object = #{<<"objectID">> => <<"1234">>, <<"content">> => <<"foo">>}.
2> algolia_index:add_object(Index, Object).

Update an existing object in the index

Replace all object attributes:

1> Object = #{<<"objectID">> => <<"1234">>, <<"content">> => <<"foo">>}.
2> algolia_index:update_object(Index, Object).

Update some object attributes (partial update):

1> Object = #{<<"objectID">> => <<"1234">>, <<"content">> => <<"foo">>}.
2> algolia_index:partial_update(Index, Object).

Apply operation on object attributes:

1> Object = #{
  <<"objectID">> => <<"1234">>,
  <<"price">> => #{
   <<"_operation">> => <<"increment">>,
   <<"value">> => 10
 }}.
2> algolia_index:partial_update(Index, Object).

Search

Search without additional parameters:

1> algolia_index:search(Index, <<"foo bar">>).

The server response will look like:

{ok, #{<<"hits">> => [
#{<<"_highlightResult">> => #{<<"content">> => #{<<"matchLevel">> => <<"full">>,
  <<"matchedWords">> => [<<"foo">>],
  <<"value">> => <<"<em>foo</em>">>}},
  <<"content">> => <<"foo">>,
  <<"objectID">> => <<"53383650">>}],
<<"hitsPerPage">> => 20,
<<"nbHits">> => 1,
<<"nbPages">> => 1,
<<"page">> => 0,
<<"params">> => <<"query=foo">>,
<<"processingTimeMS">> => 1,
<<"query">> => <<"foo">>}}

You can customize your search by providing additional parameters (see official REST API Reference) for comprehensive list of available parameters. Example:

1> algolia_index:search(
  Index,
  <<"foo bar">>,
  #{<<"hitsPerPage">> => 10}
  ).

Get an object

You can get an object using its objectID:

1> algolia_index:get_object(Index, <<"4321">>).

Optionally you can specify comma separated list of attributes that you want to receive:

1> algolia_index:get_object(Index, <<"4321">>, <<"name,age">>).

Delete on object

You can delete object by its objectID:

1> algolia_index:delete_object(Index, <<"4321">>).

Get index settings

You can receive all index settings by calling:

1> algolia_index:get_settings(Index).

The server response will look like (fragment, complete list of fields with their description can be bound in official REST API reference):

{ok, #{<<"attributeForDistinct">> => null,
  ...
  <<"snippetEllipsisText">> => <<>>,
  <<"unretrievableAttributes">> => null}},

Set index settings

To change index settings call:

1> algolia_index:set_settings(Index, #{
    <<"hitsPerPage">> => 50,
    <<"attributesToIndex">> => [<<"name">>, <<"email">>]
  }).

List indices

You can get list of all your indices together with their associated informations. Notice that this method as a parameter takes Client instead of Index:

1> algolia:list_indices(Client).

Delete an index

To delete given index call:

1> algolia_index:delete(Index).

Clear an index

To delete index contents (index settings won't be removed'):

1> algolia_index:clear(Index).
