Options to configure Lunr fields
The fields config property is passed into Lunr directly as field attributes, and can be used to configure the relative priority of different field types (e.g. title, content, keywords).
docusaurus-lunr-search sets the default value for fields to:
{
title: { boost: 200 },
content: { boost: 2 },
keywords: { boost: 100 }
}
Indexing non-direct children headings of .markdown
By default, this library will only search for headings that are
direct children of the .markdown element.
If you would like to render content inside the .markdown element on
a swizzled DocItem component, and want this library to index the
headings inside those custom elements even if they are not direct
children of the .markdown element, then add the attribute
data-search-children to a parent element of the headings you want to
index.
The data-search-children attribute will cause this library to look
for all headings inside that element, including both direct and
indirect children (E.g. 'grandchildren' nodes).
Check this issue #115 for more details.
Credits
Thanks to algolia/docsearch.js, I modified it to create this search component.
And thanks cmfcmf, I used the code from his library docusaurus-search-local for multi-language support.
