 # Unreleased: pdoc next
 
+ - **Add search functionality.**
+   pdoc now has a search bar which allows users to quickly
+   find relevant parts in the documentation.
+   See https://pdoc.dev/docs/pdoc/search.html for details.
+ - Redesign module list (index.html.jinja2).
  - Update Bootstrap to v5.0.0.
+ - Do not fail if `inspect.getdoc()` raises.

+"""
+pdoc has a search box which allows users to quickly find relevant parts in the documentation.
+This feature is implemented entirely client-side so that pdoc can still be hosted statically,
+and works without any third-party services in a privacy-preserving way. When a user focuses the
+search box for the first time, pdoc will fetch the search index (`search.json`) and use that to
+answer all upcoming queries.
+
+##### Search Performance
+
+pdoc uses [Elasticlunr.js](https://github.com/weixsong/elasticlunr.js) to implement search. To improve end user
+performance, pdoc will attempt to precompile the search index when building the documentation. This only works if
+`nodejs` is available, and pdoc gracefully falls back to client-side index building if this is not the case.
+
+If your search index reaches a size where compilation times are meaningful and `nodejs` cannot be invoked,
+pdoc will let you know and print a notice when building your documentation. In this case it should be enough to install
+a recent version of [Node.js](https://nodejs.org/) on your system and make a `nodejs` or `node` available on your PATH.
+There are no other additional dependencies. pdoc only uses `node` to interpret a local JS file, it does not download any
+additional packages.
+
+You can test if your search index is precompiled by clicking the search box (so that the search index is fetched) and
+then checking your browser's developer console.
+
+##### Search Index Size
+
+The search index can be relatively large as it includes all docstrings. For larger projects, you should make sure that
+you have [HTTP compression](https://en.wikipedia.org/wiki/HTTP_compression) and caching enabled. `search.json` usually
+compresses to about 10% of its original size. For example, pdoc's own precompiled search index compresses from 312kB
+to 27kB.
+
+##### Disabling Search
+
+If you wish to hide the search box, you can add
+```html+jinja
+{% block search %}{% endblock %}
+{% block search_js %}{% endblock %}
+```
+in your [`module.html.jinja2` template](../pdoc.html#editing-pdocs-html-template).
