The engines now all use KeyValue results and return the results in a EngineResults object. The sqlite engine can return MainResult results in addition to KeyValue results (based on engine's config in settings.yml), Signed-off-by: Markus Heiser <markus.heiser@darmarit.de>

Solr_ is a popular search engine based on Lucene, just like Elasticsearch_. But
|
|
instead of searching in indices, you can search in collections.
|
|
|
|
Example
|
|
=======
|
|
|
|
This is an example configuration for searching in the collection
|
|
``my-collection`` and get the results in ascending order.
|
|
|
|
.. code:: yaml
|
|
|
|
- name: solr
|
|
engine: solr
|
|
shortcut: slr
|
|
base_url: http://localhost:8983
|
|
collection: my-collection
|
|
sort: asc
|
|
enable_http: true
