• What is the cause and solution for SAP error message ESH_IF_INA031 - Query must not be empty; '*' is required at least ?

  The SAP error message ESH_IF_INA031 indicates that a query submitted to the Enterprise Search (ESH) interface is empty, and it requires at least a wildcard character (*) to be present in the query. This error typically occurs when a search operation is attempted without any search criteria, which is not allowed.
  Cause:
  
  Empty Query: The most common cause of this error is that the search query submitted to the ESH is empty. This can happen if the user did not enter any search terms or if the application logic fails to construct a valid query.
  Incorrect Input Handling: If the application is not properly handling user input or if there are issues in the front-end code that leads to an empty query being sent to the backend.
  Configuration Issues: There may be configuration issues in the ESH setup that affect how queries are processed.
  
  Solution:
  
  Ensure Input is Provided: Make sure that the user enters a valid search term before submitting the query. If the intention is to perform a search without specific criteria, ensure that the wildcard character (*) is included in the query.
  Modify Application Logic: If you are developing or maintaining the application, check the logic that constructs the search query. Ensure that it defaults to * or another valid search term if no input is provided by the user.
  User Interface Validation: Implement validation on the user interface to prevent users from submitting empty queries. This can include disabling the search button until valid input is provided.
  Check ESH Configuration: Review the configuration settings of the Enterprise Search to ensure that it is set up correctly to handle queries. This may involve checking the search connectors and indexing settings.
  
  Related Information:
  
  SAP Documentation: Refer to the official SAP documentation for Enterprise Search for more details on query handling and configuration.
  SAP Community: Engage with the SAP Community forums to see if other users have encountered similar issues and what solutions they have found.
  Debugging: If you have access to the backend, consider enabling debugging or logging to capture the exact query being sent to the ESH, which can help identify why it is empty.
  
  By addressing the above points, you should be able to resolve the ESH_IF_INA031 error and ensure that valid queries are processed correctly.
