Searchbox now filters Data in Grid 

I added some changes up on your code in TranslateMe and now search box is able to filter Grid data. I am using a ‘DocumentBackup’ as a main content holder  to save the addresses of the Phrases and former ‘Document’ object is still connected to Grid. 

I do filtering on original phrases come from ‘DocumentBackup’ and remove their address form ‘Document’ if they are not satisfying search criteria on NAME field. If phrases get modified then they are all accessible through ‘DocumentBackup’ and that’s where I use this object to ‘Generate’ modified RES files. 

Summary: 
A new instance of Document class called 'DocumentBackup' added to keep track of existing culture and phrases addresses. Now Document object is only used as a data container to populate grid. Typing in searchBox filters Document phrases.
