It was driven by the following use cases:
- Get list of facets (only searchable fields)
- Get list of fields with concept inference
- Get list of all fields
- Splitted in private / public fields (to define mapping)
- Get all date fields
- Get field type
- To apply sanitization rules
- To define mapping
- Check if concept inference enabled
- Check if the field is searchable
- Check if the field is a facet
- Check if the field is private
- Dereference field from label (still to be done)
(The last two UCs are new)
Also removed old code from legacy search engines.
[#PHRAS-500]
- Date and number types sanitization
- Remove `RecordIndexer` dependency on `ElasticSearchEngine`
- Move some sanitization from `RecordIndexer` to `RecordHelper`
- Index the full content of a record in a (private_)content_all field
- Handle all fields wide search as a special-case (drastically simplify queries)
- QueryContext doesn't take all allowed fields anymore, but whether private
fields are allowed or not. Since private fields are namespaced, field level
restriction is not needed anymore.
- Look for text nodes and infer the concepts behind term using thesaurus
- Use value objects for thesaurus terms and concepts
- Pass a QueryContext holding allowed fields and locales informations when building the Elasticsearch query
- Change type hinting and name of query building method on nodes
- Remove unused method Node#isFullTextOnly()
- Move getFieldsStructure from RecordIndexer to RecordHelper for reusing field structure in SearchEngine
