+<h3>Source Filters</h3>
+
+<p>
+  Source filters can be used to exclude one or more fields when fetching the document source. This happens when viewing a document in the Discover app, or with a table displaying results from a saved search in the Dashboard app. Each row is built using the source of a single document, and if you have documents with large or unimportant fields you may benefit from filtering those out at this lower level.
+</p>
+
+<p>
+  Note that multi-fields will incorrectly appear as matches in the table below. These filters only actually apply to fields in the original source document, so matching multi-fields are not actually being filtered.
