If you are thinking about creating a website where you can show your big data, then with the help of facet search your website user can actually find specific data related to them. In this blog, I will help you in setting up Facet search functionality on your data in Drupal 7.
The Faceted Search module provides a search API and a search interface for allowing users to browse content in such a way that they can rapidly get acquainted with the scope and nature of the content, and never get lost in the data. More than a search interface, this is an information navigation and discovery tool.
In order to make such functionality, you need to install some modules on your site. We will first make an Indexing engine which will index all your data, and then we will make blocks of specific data which will allow you to filter all the related data to itself.
Modules to install for implementing Facet Search:
- Facet API
- Search API
- Database search
- Search Facets
- Search Views
- Entity API
Now that we are done with installing and enabling above modules, follow the below steps. Steps to follow:
Create the content type and add fields in respective content type.
Configure the search server
configure the search index
Add fields on in Facet API
Create a complete view of your data
Each step is explained below
Step 1. Create content type and add fields in that:
Let’s take an example that we created content type
Now create content of above content type and add data into it.
Right now we have content with data into it, and also modules. Now we need to configure above modules as per our functionality on data.
Step 2. Configure the search server:
Go to configuration admin page (configuration/admin) in your Drupal 7 site and click on the search API in Search and metadata section. You should be now on Search configuration setting. We will create a search engine for our data. You should see page like below:
Now click on Add server link. Give a name to your server I gave (MYSQL), Choose database service for your service class and click create a server. Your server should be like below.
Step 3. Configure the search Index:
Now we will make our search index, which will index all data from using search server and database server. It will do indexing as the user search for data on site and give faster results. Go back to search API settings and click on Add Index link. You should be on below page now.
Values for above form:
Index name: Business Information
Item type: Node
Server: MYSQL which you create earlier
Index items immediately: Checked
Click on create Index. Now we will select which field to be indexed from our data so we will select fields we want. In our case, we will select
and click on save the configuration.
What is the outcome
we created our database server, Index server and added fields which need to be. As you added fields for indexing Facet API actually make Facet blocks of those fields.We will enable them later.
Now run Cron in your site which populate the Index.
Step 4. Create a view of your data which need to be Indexed and Displayed to your site user:
Install Views and enable it. Go to Structure > Views. click add a new view. Select below values for each field:
Show content: Business Information “This will be name of your Search server”
Create a page: checked
Display format: Table
Your view information look like below:
Click on continue & edit button. Now in the Fields section click on add fields and Filter Index node. Add Index fields you want to show to your user. Your selection will look like as below.
Complete all configuration of the specific field and click Apply Display. You are done with creating view. You are now able to see this view on your front page(/node).
Next step is to enable all blocks of your facet search. Earlier we added fields which needed to be Indexed. Actually when you add fields for indexing Facet API it creates Blocks of those fields respectively. You have to just enable them from Search settings.
Step 5. Enable Facet block from Search settings:
Go to configuration and click on Search API from search and metadata. Now just click on edit in You are able to see various configuration options like below.
Click on Facets and enable facets you want. When you enable and save the configuration, it will create blocks of respective fields.
Step 6. Enable your Facet block from Blocks:
Now go to structures and blocks. Here you are able to see your block in Disable section just enable them in any regions of your theme.
Congratulations! Your site is ready. Visit your home page and it should look like as below. As you select options from blocks your main view shows you data as per your selection.
Facet API have many configuration options. You should take a look to them like showing selection in Blocks in Checkbox etc. However, facet API is not able to give you Multiple Facet search functionality. So, I am now working on developing custom module of widget and behavior which will give functionality of Multiple facet selection search. Facet API have OR and AND but only AND works not OR among fields.
