Smart search for claims

Post by Pommes89 » Fri Oct 14, 2016 1:11 pm

i want to do the smart search with the field identifier "claim". But its not working, even with your provided example:

It says:

"An error has occurred
Invalid query
Refine search
The page you tried to display caused an error.
Error message: Unknown index. "

what is wrong?

thanks for support in advance!

Smart search for claims

Hi Patrick,

The default database behind Smart search is the Worldwide collection, this is the reason why you receive the error message if you use a full-text field identifier.

You need to refine your search and then you can select the full-text database in which you would like to search.
Kind regards,
