Fetch record using ticket number field

I want to create page for customer who can see record connected to thier ticket number. Flow of the pages are

  • customer receive URL after technician submit the page using Email submit rules
  • customer open URL where the page will ask to enter Ticket number
  • when ticket number is entered customer will see connected record to ticket number

I am not able to create such page which can fetch connected record based on ticket number
