 The mapping of the destination index - the index that contains the embeddings that the inference endpoint will generate based on your input text - must be created. The destination index must have a field with the [`semantic_text`](elasticsearch://reference/elasticsearch/mapping-reference/semantic-text.md) field type to index the output of the used inference endpoint.

-If you’re using web crawlers or connectors to generate indices, you have to [update the index mappings](https://www.elastic.co/docs/api/doc/elasticsearch/operation/operation-indices-put-mapping) for these indices to include the `semantic_text` field. Once the mapping is updated, you’ll need to run a full web crawl or a full connector sync. This ensures that all existing documents are reprocessed and updated with the new semantic embeddings, enabling semantic search on the updated data.

After your data is analyzed, click **Override settings**. Under **Edit field names**, assign `id` to the first column and `content` to the second. Click **Apply**, then **Import**. Name the index `test-data`, and click **Import**. After the upload is complete, you will see an index named `test-data` with 182,469 documents.

 ## Reindex the data [semantic-text-reindex-data]
 
 Create the embeddings from the text by reindexing the data from the `test-data` index to the `semantic-embeddings` index. The data in the `content` field will be reindexed into the `content` semantic text field of the destination index. The reindexed data will be processed by the {{infer}} endpoint associated with the `content` semantic text field.

 ## Semantic search [semantic-text-semantic-search]
 
 After the data has been indexed with the embeddings, you can query the data using semantic search. Choose between [Query DSL](/explore-analyze/query-filter/languages/querydsl.md) or [{{esql}}](elasticsearch://reference/query-languages/esql.md) syntax to execute the query.
