Install and use Solr as search engine #430

Closed steinmb closed 3 years ago

steinmb commented 4 years ago

Follow up from issue #341 where we due to time constrains by keeping the scope as small as possible choosed not to implement Solr though we in issue #36 pave way for this to happen one day.

Ref: https://lucene.apache.org/solr/

Scope

[x] Get a Solr 7.x instance that store our search indexe(s) installed on Norstore
[x] Start testing out new search on a new path, example: https://elmcip.net/test/search
[x] When we har happy, stop using MariaDB as search backend.
[x] ~~Write hook_update_N() that uninstall search_api_db or loosen the dependencies on search_api_db from elmcip_search.~~

How to test

At launch should search return about the same results as today though no facets on the test page.

https://elmcip.net/test/search - You need to be logged in to access it.

A test instance have been ordered. All we have to do now is wait.

They have a non working 7.7.x version in the works. Awaits feedback on my latest finding in the installation.

@elmcip Solr backend up and running. I will keep it in test for a few weeks to make sure it perform and is stable. https://elmcip.net/test/search a test page for the new index. The Index do not have any facets enbabled and do not contain all fields as our current but should perhaps be enough for a rough test.

Works as a rough test, though we want the facets and the same preview as we currently have. But the relevance actually seems better.

Solr have been stable. Going to swap out the search backend storage in productions. Remove needs review tag.

Swaped out MariaDB as search backend.
Removed test search page
Removed MariaDB search backend config, make sure we drop all old indexed data
Reindexed with Solr
Going to keep search_api_db in the application stack. Useful for local testing if people do not have a Solr instance available.
