Search feature does not work

[TravisJ 0]

I'm using Evernote on a Mac, and have used it for years, but recently the search feature has stopped working effectively. When I type in a word that I'm certain I've made notes about, nothing shows up in the search results. Only notes in the current year appear, but I need to find notes from years ago without scrolling through each one. Does anyone know how to fix this? It's very frustrating.
