Fast search results after the first search?

What exactly is responsible for this and is there is a way to make it permanent.

For example if I search my 2tb hdd,the first time it will take some time to display the result but after that,everything I search for is displayed much much faster.

Search indexing is disabled and I know about the program Everything and similar

I would enable Search Indexing to make searches much faster, include everywhere you want searched including external drives when they are plugged in. If it becomes slow for any reason, just rebuild the Index.
