Verify Custom Chunking Results
After your search index has run and reached a Ready status, verify that your custom chunking function produced the expected chunks. Inspect the chunk data in Data Explorer and, optionally, validate search behavior by using a retriever and Prompt Builder.

- A search index that uses your custom chunking function and has run successfully, meaning Search Index Last Run Status is Ready.
Chunking runs only on content that was successfully ingested into the source you selected for the search index. If you expected chunks from a document, for example, a PDF, but see none, verify that the document uploaded and ingested successfully into that data source before the search index ran. A failed or incomplete upload means there is no content for the function to chunk.
-
Open the search index record and note the Chunk Data Model Object name listed on the page.
-
In Data Explorer, select the appropriate data space, object type as Data Model Object, and the data model object name that corresponds to the chunk data model object from your search index.
-
Open a row to view the chunk data and confirm that text, sequence numbers, and citations match what your custom function is designed to produce. Check that each chunk retains the context you intended (for example, a section heading with its content, or a product name with its description). Contextually coherent chunks lead to more accurate search and AI retrieval.
