Ok, when I do a search, I get search results, but I don't think I'm getting all of them. Like, I'll search for a song, and on the tab at the top, it'll say the name of the song, and a number like (150), but in the results, I only see like 20. Is there anyway to fix this, and see all the results?

the 150 represents the overall quality of the files in view. Not the actual number of files. If you add up all the numbers in column 2 and add 1 foe each file not showing a number, you will get 150.
