Add support for additional search providers

[mmistakes]

Augment search feature by allowing support for different search providers, similar to what was done with commenting.

• GitHub Pages compatible search (Lunr.js default)
• Algolia, powered by jekyll-algolia plugin
• Google Custom Search Engine
• Other

@mmistakes Would you also be interested in multiple language support ?

[mmistakes]

Not sure I follow what you mean by multiple language support @nickgarlis. Could you expand on it some?

[nickgarlis]

@mmistakes I am not sure about Algolia but Lunr does not support any other languages other than English by default. Non English users might be interested in searching in their native language.

My solution to this was to use a different .js file for the extra language that I wanted to support where I registered a new stemmer.

We could also borrow some stemmers from this repository

Ah ok. Yeah I dunno. If it can be done in a way to not over complicate setup. In my experience it can be tricky handling multiple languages with a theme because Jekyll core isn’t really all that friendly to it.

Last thing I want to do is open a can of worms that can’t be supported well.

[mmistakes]

@nickgarlis Possible solution would be leverage site.locale set in _config.yml. This could be used to determine what language .js to load. Since locale can be language and locale (eg. en-US) doing something like this would normalize it to just the language.

{% assign lang = site.locale | slice: 0,2 | default: "en" %}

Then you could load the appropriate .js and if one doesn't exist for the given locale default to English.

<script src="{{ '/assets/js/lunr-{{ lang }}.js' | absolute_url }}"></script>

[nickgarlis]

That's exactly how I was thinking of doing it !

For what it's worth, Algolia is language agnostic :)

Is there anything I could do to help you integrate jekyll-algolia?

[mmistakes]

@pixelastic It's on my todo list. I just need to lay the ground work for it in the theme.

Has a pull-request #1531

[user414]

First thanks for the great theme @mmistakes, very useful. Should we keep this request open since google CSE is still not supported or should we open a new one to keep track of it? We were also looking to support google CSE and came upon this issue.

[mmistakes]

@user414 Open a new issue so it can be tracked, if and when I get around to it.
