DocPad Lunr Plugin

Generates Lunr search indexes from your Docpad collections, and provides helpers for a client-side full-text and faceted search.

Getting Started

npm install --save docpad-plugin-lunr


docpad install lunr

Configure a collection to index in your

        collection: 'myCollection'

To create an index which includes multiple collections you can pass an array of collection names:

        collection: ['firstCollection','secondCollection']

Make your search page itself, eg

<%- @getLunrSearchPage('myIndex') %>

Make a "search bar" on other pages that redirects users to your search page above, like in a layout, eg.

<%- @getLunrSearchBlock('my-search-page.html') %>


To control the fields that get indexed and their "boost" levels (ie, relevance), add to the index's configuration in

indexFields: [
  {name: "body"boost: 1}
  {name: "title"boost: 10}
  {name: "tags"boost: 100}

To control the fields that are available in search results, add to the lunr configuration in

contentFields: [
  {name: "title"}
  {name: "url"}
  {name: "date"}

For faceted search, add to the lunr configuration in

facetFields: [
  {name: "tags"label: "Filter by tag"}
  {name: "type"label: "Filter by type"}

(Note: the faceted search is not part of Lunr, just my own poor-man's version. Also, you may want to put in a bit of CSS to highlight the "active" facet filters, such as: <style>.active:after{content:'*';}</style>.)

To provide an Eco template for the search-results, add to the lunr configuration in

resultsTemplate: 'src/partials/'

Then in src/partials/

  <a href="<%= post.url %>"><%= post.title %></a>
  <span>posted on <%= %></span>

Or provide a template function for search results directly in

resultsTemplate: (context) ->
  post =
  return """
    <a href="#{post.url}">#{post.title}</a>
    <span>posted on #{}</span>

To add your own "stopwords" to prevent certain words from being indexed, add to the index's configuration in

stopWords: ['an','array','of','words']

Advanced usage

If you want to make your own UI (and your own implementation of facets), here are the basics:

<script src="/lunr/lunr.min.js" type="text/javascript"></script>
<script src="/lunr/lunr-data-myindex.js" type="text/javascript"></script>
<script type="text/javascript">
  lunrdoc.idx = lunr.Index.load(lunrdoc.indexJson);
  var results ='this is your user input');
  for (var i in results) {
    var itemData = lunrdoc.content[results[i].ref];
    var renderedItem = lunrdoc.template({post: itemData});


  • Currently this plugin is geared towards static sites, and brings everything client-side. Need to allow for dynamic sites to take advantage of having a back-end - ie, keep the index, searching, and content on the back-end.
  • Hopefully if faceted search is added to Lunr proper, re-implement using that
  • Failing that, add more facet types, like dates and numeric ranges
  • Allow for custom pipeline functions
