add matcherFunction and matchOnElement options

README.md

@@ -57,6 +57,8 @@ This plugin provides the following configuration options:
 | onSearchFocus | `false` | Allows you to define a function to be called when the search input is focussed. The `this` context of this function will be the search input element. |
 | onSearchBlur | `false` | Allows you to define a function to be called when the search input is blurred. The `this` context of this function will be the search input element. |
 | clearOnLoad | `false` | Determines whether the search input should be cleared on page load (either `true` or `false`). |
+| matcherFunction | `null` | A custom matcher function. Should return a function to be run against each `childSelector`. |
+| matchOnElement | `false` | If `true`, the element identified by `selector` is provided to the matcher function. If `false`, jQuery `.text()` is called on it first. Useful if `matcherFunction` provided. |

 - Added some events that allow you to call custom functions during the search lifecycle: onSearchActive, onSearchEmpty, onSearchFocus, onSearchBlur (view the [configuration](#configuration) for more information).
 - Added the `clearOnLoad` setting which allows you to clear the search input on page load / refresh.
