I'm looking for a better way to return content in order to allow access to sub title.

I'm looking for a better way to return content in order to allow access to sub title.

I think that I will pivot to Minisearch https://lucaongaro.eu/blog/2019/01/30/minisearch-client-side-fulltext-search-engine.html

Hello @atinux,

Sorry, I take some times to improve this PR! I've written documentation but I'm open to suggestions.

I will wait for @farnabaz deep review since he is the lead of Nuxt Content

[Barbapapazes]

Hello,

I refactor a lot using your comments @farnabaz! Hope this is better now!

Thanks @Barbapapazes,
Looks good to me, I'll move the module option under experimental, and we will make it an official feature in v3
