Add Appointment's Customer to title header in recent search history preview.

It looks correct. Since you’re likely wanting Customer.acctCD and not the customerID I would suggest using Customer.acctCD instead of FSAppointment.customerID to start with.

Then, after publishing, do a rebuild.

If this is a local install, you can review the results of the re-build by examining the SearchIndex table to see if the issue is that the SearchIndex.Content field is not being updated or if the display of the search results is the issue (which might just require a site restart to fix).

thank you for your response,

I followed all of your instructions, but now neither the title heading nor Line 1 are showing the customer.
Also, the customer was not visible in the database.

Any other suggestions

Hi @srikanth56  were you able to find a solution? Thank you!
