Querying Lieu

Search Syntax

• cat dog - search for pages about cats or dogs, most probably both
• fox site:example.org - search example.org (if indexed) for term "fox"
• fox -site:example.org - search all indexed sites except example.org for term "fox"
• emoji lang:de - search pages that claim to mainly contain German content for the term "emoji"

When searching, capitalisation and inflection do not matter, as search terms are:

• Converted to lowercase using the go standard library
• Passed through jinzhu's inflection library for converting to a possible singular form (intended to work with English nouns)

Search API

Lieu currently only renders its results to HTML. A query can be passed to the / endpoint using a GET request.

It supports two URL parameters:

• q - used for the search query
• site - accepts one domain name and will have the same effect as the site:<domain> syntax. You can use this to make your webrings search engine double as a searchbox on your website.

Examples

To search example.org for the term "ssh" using https://search.webring.example:

https://search.webring.example/?q=ssh&site=example.org

Adding a form element, to use Lieu as a search engine, to the HTML at example.org:

<form method="GET" action="https://search.webring.example">
	<label for="search">Search example.org</label>
	<input type="search" minlength="1" required="" name="q" placeholder="Your search query here" id="search">
	<input type="hidden" name="site" value="example.org"> <!-- This hidden field tells lieu to only search example.org -->
	<button type="submit">Let's go!</button>
</form>
