Algolia DocSearch integration: expose some additional APIs in hugo.toml

[hurrellit]

I'm using Algolia DocSearch for the search system on my Hugo/Docsy doc site (I cannot use Lunr as the site is quite large creating a huge index) and having battled with the Algolia Crawler to build a search results index that is acceptable (this is another story as I found the DocSearch crawler config very much a black box and difficult to understand), I recently wanted to increase the number of search results that are returned per "group". The default is 5 results and this is quite a low number....

I discovered that it is possible to change this default value using the API maxResultsPerGroup (see https://docsearch.algolia.com/docs/api/#maxresultspergroup). I then found that Algolia DocSearch is defined in Docsy within the /layout/partial/scripts.html file and that by creating my own scripts.html override file and adding maxResultsPerGroup in, I was able to change this behaviour:

It would be really good to be able to add in these Algolia DocSearch API options directly in the hugo.toml file under [params.search.algolia] - this would avoid having to create an override partial to do it.

Or is there a better way to do this that avoids having to create a scripts.html partial?
