Make Queries Configurable

[trieloff]

In addition to allowing to specify how the index should be populated, the queries.yaml should also specify the queries that can be run against the index. See the example below:

#
# index configuration for theblog (hackathon vii)
#
version: 1
​
indices:
  blog-posts:
    source: html
    fetch: https://helix-norddal-anfibiacreativa.project-helix.page/{path}
    ranking:
      - "desc(date)"
      - typo
      - words
      - filters 
    properties:
      author:
        select: .blog-author p a
        value: "{textContent}"
        faceted: true
      title:
        select: h1:first-of-type
        value: "{textContent}"
      date:
        select: ".blog-author p:nth-child(2)"
        value: "{parseTimestamp(\"[POSTED ON] MM-DD-YYYY\")}"
      topics:
        select: .blog-topics.default > ul > li
        value: "{textContent}"
        faceted: true
      hero:
        select: main > div > img:first-of-type
        value: "{src}"
    queries:
      all:
        query: *
        hitsPerPage: 25
        cache: 10 minutes
      by-author
        parameters:
          - author
        query: *
        filters: author:{author}
       cache: 5 minutes

This would enable two query endpoints:

• _query/blog-posts/all
• _query/blog-posts/by-author?author=Lars+Trieloff

The query configuration would be read during hlx publish and the proper VCL would be generated to forward the query to Algolia or MongoDB.
