Best Practices for Displaying User's Last 3 Searches

Hi @aidanb 

I believe the best way to implement this is through Collections. However, if that it is not possible you can do the ff. below:

1. Capture Search Events: Whenever a user performs a search, you should trigger a custom event in Customer.io.

2. Update Last 3 Searches Attribute: In the same event, you need to update a custom attribute that keeps track of the last 3 searches. You can use Liquid to manipulate this attribute:

   • {% assign lastSearches = customer.last_searches | default: "" | split: ", " %} {% assign newSearch = "Last search " | append: lastSearches.size | append: ": Nike" %} {% assign lastSearches = lastSearches | push: newSearch | slice: -3, 3 | join: ", " %} {% update_attributes "last_searches": lastSearches %}

     This does the following:

   • Initializes an array lastSearches to store previous searches.
   • Creates a new search string based on the search count.
   • Appends the new search to the array and limits it to the last 3 searches.
   • Updates the custom attribute last_searches with the updated list.

3. Display Last 3 Searches in Broadcasts: When you send broadcasts, you can use Liquid to display the last 3 searches for each user:

   • Your Last 3 Searches: {{ customer.last_searches | default: "No searches yet." }}

     This Liquid code will display the user's last 3 searches or a default message if there are no searches yet.

4. Handle Edge Cases: Ensure that your Liquid logic handles cases where there might be fewer than 3 searches or if there are no searches at all.

By implementing this logic, you'll be able to dynamically track and display the last 3 searches for each user in your broadcasts.
