 You must at least provide the `fields` you want to index.  If the language isn't English, you must pass in the `language` option.  Boosts don't matter.
 
+### Passing Options to lunr.js during build
+
+You can pass in options to lunr.js during the index build by adding a `lunrOptions` option to the search. `lunrOptions` is a function whereby you can access the lunr instance via `this` from within the function. For example, if you wanted to add a function to the pipeline, you could do it like so:
+
+```js
+pouch.search({
+  fields: ['title', 'text'],
+  build: true,
+  lunrOptions: function(){
+    this.pipeline.add(function (token, tokenIndex, tokens) {
+      // text processing in here
+    })
+  }
+});
+```
+More info on the lunr.js methods available here: http://lunrjs.com/docs/
+
 ### Deleting the index
 
 If, for whatever reason, you need to delete an index that's been saved to disk, you can pass in `{destroy: true}` to the `search()` function, and instead of searching, it will delete the external search database.
