Azure AI Search: Newly Added Filterable Fields Not Populating After Indexer Run

Question

I recently added two new fields to my Azure AI Search index and marked them as filterable. After updating the index schema and running the indexer, the new fields are still not populated in the index.

Steps Taken So Far:

• Ran the indexer to pull in the new data from the data source.
• Verified that the data source contains values for these fields.
• Checked the index definition in Azure Portal, and the fields appear correctly.

Questions:

• Do I need to reset or delete the indexer before the new fields can populate?
• Is there a way to force Azure Search to re-index only the new fields?
• Could this be due to indexer caching or an issue with field mappings?

Any guidance on troubleshooting this issue would be greatly appreciated!

I also tried an alternative approach by creating a new index. This time, the fields are populated, but they are no longer filterable.

This is the first Index where I have added new fields manually
