Search And Compile Multiple Spreadsheets

The company deals with Machine services, we maintain, service and brake-fix machine problems, the machines are manufactured my ourselves and there are approximately 15 different machines.

We have a Field Service spreadsheet that is filled in by all service engineers for every job they go on, this is filled in with information like:-

Serial Number
Machine Type
Hours Run Time
Reason for Visit
Reported Problem
etc, etc

All the forms are identical so all the fields are identical

Field Service Record Spares 2013 Master Rev4 (2).xlsx (this is the correct file). The forms are then saved on a central server folder and stored in month order.

Is there a way of creating a master excel sheet to gather all the information from all the Field Service spreadsheets which would then allow me to search all sheets by serial number or fault, without me having to copy and paste all the information into the master sheet??

We have 10 service engineers and each fills out 1 sheet per job per week, so a 4 week job will have 4 sheets for 1 engineer. an engineer could go on 5 jobs in 1 week and would therefore fill out 5 sheets. so we could be looking at in excess of 500 Field Service spreadsheet per year.
