We added an option in Copernic Desktop Search 7.1 in file indexing options (Tools menu > Options > Files) to speed up the indexing from selected directories. In other words, it means that scanned folders that has the "index in priority" mode on, will be added to a priority queue for future manual or scheduled index updates.

When Copernic Desktop Search is scanning for new files or modified files, this option allows the program to create a priority indexing queue for files located in the selected folders. 

Important: It doesn't mean that those files will be immediately indexed. The indexing process will still continue indexing files and folders that are already in the queue, but the priority order will be taken at the next index update.

This option will not affect other priority orders from other sources like emails.
