DocSearch can work with almost any website, but we've found that some site structures yield more relevant results or faster indexing time. In this page we'll share some tips on how you can make the most out of DocSearch.
If you provide a sitemap in your configuration, DocSearch will use it to directly browse the pages to index. Pages are still crawled which means we extract every compliant link.
We highly recommend you add a
sitemap.xml to your website if you don't have
one already. This will make the indexing faster, but will also give you more
control over which page you'd like to include or not in the indexing.
Sitemaps are also considered good practice for other aspects, including SEO (more information on sitemaps).
DocSearch works better on structured documentation. Relevance of results is
based on the structural hierarchy of content. In simpler terms, it means that we
<h6> headings of your page to guess the hierarchy of
information. This hierarchy brings contextual information to your records.
Documentation starts by explaining generic concepts first and then goes deeper
into specifics. This is represented in your HTML markup by the hierarchy of
headings you're using. For example, concepts discussed under a
<h4> are more
specific than concepts discussed under a
<h2> in the same page. The sooner the
information comes up within the page, the higher is it ranked.
DocSearch uses this structure to fine-tune the relevance of results as well as to provide potential filtering. Documentations that follow this pattern often have better relevance in their search results.
Finding the right depth of your documentation tree and how to split up your
content are two of the most complex tasks. For large pages, we recommend having
4 levels (from
lvl3). We recommend at least three different levels.
Note that you don't have to use
<hX> tags and can use classes instead (e.g.,
<span class="title-X"> ). You will need to update the
DocSearch extracts content based on the HTML structure. We recommend that you
add a custom
class to the HTML element wrapping all your textual content. This
will help narrow selectors to the relevant content.
Having such a unique identifier will make your configuration more robust as it will make sure indexed content is relevant content. We found that this is the most reliable way to exclude content in headers, sidebars, and footers that are not relevant to the search.
When using headings (as mentioned above), you should also try to add a custom
anchor to each of them. Anchors are specified by HTML attributes (
id) added to headers that allow browsers to directly scroll to the right
position in the page. They're accessible by clicking a link with
# followed by
DocSearch will honor such anchors and automatically bring your users to the anchor closest to the search result they selected.
If you're using a multi-level navigation, we recommend that you mark each active level with a custom CSS class. This will make it easier for DocSearch to know where the current page fits in the website hierarchy.
For example, if your
troubleshooting.html page is located under the
"Installation" menu in your sidebar, we recommend that you add a custom CSS
class to the "Installation" and "Troubleshooting" links in your sidebar.
The name of the CSS class does not matter, as long as it's something that can be used as part of a CSS selector.
Consistency is a pillar of meaningful documentation. It increases the intelligibility of a document and shortens the time required for a user to find the coveted information. The document topic should be identifiable and its outline should be demarcated.
The hierarchy should always have the same size. Try to avoid orphan records such as the introduction/conclusion, or asides. The selectors must be efficient for every document and highlight the proper hierarchy. They need to match the coveted elements depending on their level. Be careful to avoid the edge effect by matching unexpected superfluous elements.
Selectors should match information from real document web pages and stay
ineffective for others ones (e.g., landing page, table of content, etc.). We
urge the maintainer to define a dedicated class for the main DOM
container that includes the actual document content such as
Since documentation should be interactive, it is a key point to verbalize concepts with standardized words. This redundancy, empowered with the search experience (dropdown), will even enable the learn-as-you-type experience. The way to find the information plays a key role in leading the user to the retrieved knowledge. You can also use the synonym feature.
The more time-consuming reading documentation is, the more painful and reluctant its use will be. You must avoid hazy points or catch-all. With being unhelpful, the catch-all document may be confusing and counterproductive.
Duplicates introduce noise and mislead users. This is why you should always focus on the relevant content and avoid duplicating content within your site (for example landing page which contains all information, summing up, etc.). If duplicates are expected because they belong to multiple datasets (for example a different version), you should use facets.
What is clearly thought out is clearly and concisely expressed.
