How to install wikimedia extra plugin for elasticsearch?-CodePudding

I am trying to install the org.mediawiki.search extra plugin for elasticsearch. I am running elasticsearch 7.17.2 locally, however the plugin seems to be available for elasticsearch 7.10.2 or older.

When I try to install it through the elasticsearch plugin installer, as suggested in the repository, I get

$ ./bin/elasticsearch-plugin install org.wikimedia.search:extra:7.17.2-wmf1
-> Installing org.wikimedia.search:extra:7.17.2-wmf1
-> Downloading org.wikimedia.search:extra:7.17.2-wmf1 from maven central

And if I specify the latest available version, I get

$ ./bin/elasticsearch-plugin install org.wikimedia.search:extra:7.10.2-wmf1

Notice that, in the latter, it downloads the file but refuses to install it because of non-matching elasticsearch versions.

Does this mean that I just can't install the plugin for my specific version of elasticsearch? Do I need to downgrade to version 7.10.2 to use this plugin? Or perhaps I can download the appropriate version of the plugins from a different place?

Thanks in advance!

CodePudding user response：

Here, it says

You will have to release a new version of the plugin for each new elasticsearch release. This version is checked when the plugin is loaded so Elasticsearch will refuse to start in the presence of plugins with the incorrect elasticsearch.version.

So you need to find the plugin which is build for your elasticsearch version, and it looks like it doesn't exist, or you need downgrade your elasticsearch to your current plugin's version, which is 7.10.2.
