The content searching feature allows your users to ask a question to your chatbot using natural language, and get the chatbot to find the answer in your knowledge base(s).
It’s an incredibly valuable feature to leverage, as it means you can set up a fully intelligent chatbot in just a few clicks.
Below, we go through each step required to set a content search chatbot.
Step 1: Activate semantic search
Semantic search, a fancy way of saying content search, needs to be activated.
To do so, head over to Settings → Semantic search. Click Activate.
Step 2: Create a knowledge base
Before we allow users to search anything, we need to feed the chatbot information. To do this, we’ll use knowledge bases.
Get a refresher on knowledge bases.
Head over to Knowledge → Knowledge bases.
For the purpose of this doc, we’ll imagine we are creating an HR chatbot. The knowledge we want to inoculate into the chatbot is the entire company’s employee handbook. It’s a big, 50+ pages-long PDF.
Content searching works with any type of knowledge bases, not just PDFs.
Name your knowledge base.
Select PDF as the Type.
Click Select file and find the file in your computer folders.
Files must be .pdf and a maximum of 6MB. You can use this tool to shrink your PDF if it’s too large: https://shrinkpdf.com
Depending on the length of the document you’ve uploaded, it may take a few minutes to process. Once it’s done, you should see your new knowledge base, along with every single article listed under it.
Step 3: Clean up your content
If you did import a PDF or even a sitemap, chances are some of your content might need a bit of cleaning up. The platform does its best to extract content, but sometimes design elements get in the way.
Go through each page and use the editing features to make your content picture-perfect.
After every article update, click Submit revision.
Then, head over to Versions
Find your latest revision in the list and click View.
Give your revisions a final read, and if you’re happy click Approve.
Step 4: Make your content searchable
Now that you have set up your knowledge base and cleaned up your content, it’s time to make it searchable.
In the left-hand side menu, click on your knowledge base’s name.
In the settings, select the articles you’d like to make searchable. If you are happy with your entire knowledge base being searchable, click Select all.
Step 5: Create a content search conversation
The content search feature is a conversational event. It was specifically designed so you can trigger it at any point in a conversation.
For example, your chatbot might allow employees to book time off. This is a standard and simple conversation to automate with the chatbot platform.
At the end of this conversation, you could add a final step such as ‘Any other questions?’, where the content search takes over.
For the purpose of this doc, we’re going to build a content search conversation from the ground up.
Head over to the Builder.
Click + Conversation in the top right. Give your conversation a name and a description.
For the trigger, let’s set up a placeholder trigger such as
When message equals search
The first step of the conversation will inform chatbot users that they can ask a question. Hit Options on the step and scroll down to Message content.
Write a short message such as: “I can help you find answers in our employee handbook. Just ask me a question”. Hit Save.
Now, we need to add a new step that will contain the answer to the user’s question.
Click the + button below the existing step.
Give the step a name.
In transition, find the event
Content import is triggered.
In the next panel, we enter the variables related to the content import. Once a user asks the chatbot a question, those variables will be populated by the appropriate answers.
Change the message type to Content.
In the message field, add a short message such as “Here’s what I found”.
In the content title field, add the knowledge base name variable,
In the content body field, add the knowledge base content variable,
Step 6: Test your content search conversation
Go to Demo.
Use the keyword you’ve set up to trigger the conversation (here “search”).
Ask a question related to the content you’ve uploaded into the chatbot. The chatbot will respond with your content message. Click View to see the section of content your chatbot has identified contains the answer to your question.
Congratulations, good to go!
