Implement ElasticSearch module

[sebastienros]

Same as Lucene

[hishamco]

You read my mind, yesterday I was read a great post on ElasticSearch

[hishamco]

FYI this is a good article https://khalidabuhakmeh.com/search-experiences-for-your-aspnet-core-apps-with-elasticsearch

Hi! I work for Elastic feel to to @ me on PR's happy to help/answer questions.

[hishamco]

@Mpdreamz if you are interested you could start in the PR for this module

[Skrypt]

The ElasticSearch module should leverage Nest for Queries. We have now Lucene Queries which uses the Lucene Query API but ElasticSearc has already this done with Nest. So we should end up with ElasticSearch Queries that should be quite the same than Lucene Queries with some small differences here and there since Nest for example can use Exists Queries.

[Skrypt]

I think we need to first make a service to retrieve different Indexing Providers. And I think we should be able to still use Lucene and/or ElasticSearch at the same time.

@Mpdreamz thanks for proposing to help us!

[cjkihl]

+1 for this feature. 👏

Is there an interface(s) I can implement to integrate Elasticsearch ?
Any docs etc to point us in the right direction ?
Thanks again

[sebastienros]

@mickdelaney no special interface, just copy paste the lucene module and adapt to use elasticsearch instead.
Many things will be the same, like the index management, or search page, or queries. They could collide if they are enabled at the same time, but they are not supposed to be.
Feel free to ask questions on gitter or join the triage meetings when you are stuck.

@sebastienros @jtkech @deanmarcussen @hishamco

We have implemented ElasticSearch (Basics in place), Index(Create, Delete, Rebuild), Indexing and Query using DSL.
Both (Elastic and Lucene can co-exist) ;-)

There are couple of observations, though

1. Lucene Content Search Picker should be better named as "Search Content Picker"? and the result provide must be abstracted higher.
2. The queries module is wired to be a sub node of Lucene Search Module
   So we can only see queries module when Lucene is enabled.

Please guide how to proceed on this.

The implementation is very basic/raw but does what is intended.

[jtkech]

@Sen-Gupta Cool !

@Skrypt is better placed to give you some feedbacks, as he is the Lucene expert

Anyway, feel free to open a PR with your suggested code

[Skrypt]

Well, first thing is to have a branch or PR to work with. Then, we can make the changes in that branch if needed.

[giannik]

@Sen-Gupta is there a public repo to try out the elastic search module ?

[Sen-Gupta]

@giannik This should be pushed potentially tomorrow! Been stuck on another Solr Search Implementations!
This works but is just the starting point!

[Sen-Gupta]

The PR can be seen here #9108

Can u make a tutorial for a step by step how to enable elastic search for orcahrd core? I am not able to enable elastic search UI on my admin interface
