 Limit how many times the search function can be executed over the given time window. This is especially useful to improve the user experience when searching over a large dataset (either with rare terms or because the number of posts to display is large). If no `debounceTime` (milliseconds) is provided a search will be triggered on each keystroke.
 
+## highlightMatchedText (value, query, snippetLength)
+
+A helper function that might be useful in `templateMiddleware` (or anywhere else).
+See [default layout](example/_layouts/default.html) for an example of usage.
+
+### value (String)
+
+The matched text.
+
+### query (String)
+
+The text that was searched for.
+
+### snippetLength (Number) [optional]
+
+The length to trim the text to.
+Defaults to 200.
