+This file exists solely to respond to /search URL with the related `search` layout template.
+
+No content shown here is rendered, all content is based in the template layouts/page/search.html
+
+Setting a very low sitemap priority will tell search engines this is not important content.
+
+This implementation uses Fusejs, jquery and mark.js
+
+
+## Initial setup
+
+Search  depends on additional output content type of JSON in config.toml
+\```
+[outputs]
+  home = ["HTML", "JSON"]
+\```
+
+## Searching additional fileds
+
+To search additional fields defined in front matter, you must add it in 2 places.
+
+### Edit layouts/_default/index.JSON
+This exposes the values in /index.json
+i.e. add `category`
+\```
+...
+  "contents":{{ .Content | plainify | jsonify }}
+  {{ if .Params.tags }},
+  "tags":{{ .Params.tags | jsonify }}{{end}},
+  "categories" : {{ .Params.categories | jsonify }},
+...
+\```
+
+### Edit fuse.js options to Search
+`static/js/search.js`
+\```
+keys: [
+  "title",
+  "contents",
+  "tags",
+  "categories"
+]
+\```
