Searching the Knowledge Base with leading wildcard in the Service Portal creates performance issue

Based on this documentation 

Wildcard characters allow searching for patterns and variations (servicenow.com)

we activated Wildcards (e.g. *) in the (Zing) search for our Knowlegde Base via Service Portal with this result: 

  • Searching for a string with a wildcard at the end (like clipboar* to find results for clipboard) works as expected within less than 2 seconds. -> OK
  • Searching for a string with a wildcard at the beginning (like *lipboard) also opens the expected results (here 2 matches) but with a searching time of > 2 minutes. If I use % as leading wildcard (%lipboard), the search takes ~1,5 minutes.

Did anyone experience similar or can give me a hint what could be wrong (we're currently on Utah)

 

Thanks
Joachim
