When you use Find in Files with Sublime Text and you are using Gulp you probably have a zillion files in the node_modules directory which will probably pollute your search results.
You can exclude stuff on the Where line by using a -.
Here is what I have found useful to exclude using the Where box:
-node_modules/*,-_assets/*,-_site/*
This is excuding node_modules, the _site folder and the assets folder where I keep all the CSS, images and JS.
