Create an advances Search system for Drupal 8 with Search API.

Search API and Database Search server.

1. Uninstall drupal basic Search

2. Install search_api and search_api_db

  NOTE : You can also use another database configures on settings.php

3. Add a Search Server (/admin/config/search/search-api/add-server).

  - Use "Database" as cackend server.

3. Add a Search Index (/admin/config/search/search-api/add-index).

  - Select Enteties (Data source) to index with this index and a search server.

  - Save and Add fields to Index. (Example : Title, Body file for "Contents").

  - Optionaly you can configure "Processors" as Filters, Data traitements ...

4. Enable the newly created "Index" then run indexing or queue indexing.

5. Create a view using your Index, and add field "Search: Fulltext search" as Exposed criteris filter.

Once indexing is done, visit the view's page to use the search system.

Tips : For a quick start, just install the "Database Search Defaults" (), and configure your "Search Server", "Index" and "Search Pages" on.

 - Search API :        /admin/config/search/search-api

 - Search Views :    /admin/structure/views (Defaut : /admin/structure/views/view/search_content )

NOTE : To create a server like Solr, Elasticsearch you need to install search server and the drupal module for those servers.

#Some usefull Drush commands for the search api and facets

Enable Facets With search API (Example : Db serch)

2. Enable facets module for drupal 8

3. Create a Search server and Search Index (at last one search index)

4. Add fields for the index.

    -> Index -> Fields -> "Add field"

5. Create a view to display your search index

6. Create a facet from /admin/config/search/facets -> "add facet" (/admin/config/search/facets/add-facet)

7. Select your facet source (Search view) and Field.

    -> For Tags or entity reference, enable '' and  ''
