Sitecore : Dynamic Tag Enhancement for Algolia Search Provider

While integrating Sitecore with Algolia Search Provider, I encountered a scenario where I needed to add many fields dynamically. The field name and value are both dynamic based on the content page.

Initially, I thought of it as a computed field, but then the field name is dynamic, and I was wondering how to add dynamic fields to the Index records.

The TagProcessor comes to the rescue – The existing Tag Processor ensures that tags are dynamically added, structured, and optimized before indexing, which outputs _tags in the indexing record.

Algolia Record Search:

The config for the existing tag processor looks like this –

AlgoliaConfiguration.sc1021.config:

CategoryDataProcessor:

Since we needed to incorporate dynamic tags into our project, I began exploring the functionality of AlgoliaTagsProcessor. Creating another Tag processor, for example, CategoryDataProcessor –allowed us to generate dynamic tags efficiently.
The ProcessDocument method ensures that the Sitecore items being processed match the expected Category Listing Template.
After Processing, the extracted data is added dynamically to the JObject doc to the Alglolia Index record.

However, this overwrites the existing_tags in Algolia index. I’m looking for a way to make both work together while also allowing the flexibility to add more dynamic tags in the future if needed.
Adding a wrapper class – AlgoliaCustomTagProcessor, which should loop through each Processor and call the ProcessDocument method.
This will ensure that each TagProcessor is called and doesn’t overwrite the existing _tags.

AlgoliaCustomTagProcessor:

AlgoliaDocumentBuilder:

Modify the AlgoliaDocumentBuilder to process both tag documents –

Initialize the new CustomTagProcessor in the Constructor.
Add the GenerateCustomTags() method, which should call ProcessDocuments in the CustomTagProcessor class.

The following is the modified AlgoliaDocumentBuilder code –

AlgoliaConfiguration.sc1021.config:

Let’s add the new CustomTagProcessor to the config file.
Now, we have two tag processors nested into each other and wrapped into our CustomTagProcessor class.
It can be extended to any dynamic Tags we want in the future.

The final dynamic category tags were added to the Algloia record, yay!

It worked!
