Troubleshooting tips for using the {{site.data.keyword.discoveryshort}} service.
If you encounter problems when using the {{site.data.keyword.discoveryshort}} service, try one or more of the following troubleshooting tips.
-
A document can fail to be ingested because of a type mismatch between data in the current document and similar data in a previously ingested document. For example, a field might be typed as a date in one document and a string in a subsequent document, preventing the subsequent document from being indexed correctly.
The preview operation cannot predict type mismatches because it tests only a single document and does not keep a record of the conversion results.
-
Rapid or large-scale indexing of documents can sometimes result in the back-end search service restarting. If this occurs, contact {{site.data.keyword.IBM}} support for assistance.
