[nodebb-plugin-solr] Solr search plugin

[a_5mith]

Will be keeping an eye on this, was a pain setting up db search once I'd imported my forum, so will have to see how this one copes with the initial indexing.

[julian]

For reference, it indexed this forum (about 12k posts) in about 4 seconds.

I was thinking about it for long time Solr, Elastic search. Is this forum now using solr ?

[julian]

Yes, @kinderjaje, when v0.1.0 was released (yesterday afternoon), I implemented it onto this forum, you can test it right now.

@julian I want to use this plugin and I have updated lastest NodeBB and Solr, but when I run ./nodebb dev, I got these warns:

warn: [plugins/nodebb-plugin-solr] This plugin may not be compatible with your version of NodeBB. This may cause unintended behaviour or crashing.
warn: [plugins/nodebb-plugin-solr] In the event of an unresponsive NodeBB caused by this plugin, run ./nodebb reset plugin="nodebb-plugin-solr".

And when I use this I got some other errors. So what shoud I do to make this work?

[a_5mith]

Pylon can safely ignore warns about plugin incompatibility, this usually means that at some point in the future, a hook will be removed in favour for another one.

What are the errors you see when trying to actually run solr?

[trevor]

So we have to install Solr first, correct?

How To Install Solr on Ubuntu 14.04 | DigitalOcean

Solr is a search engine platform based on Apache Lucene. It is written in Java and uses the Lucene library to implement indexing.

(www.digitalocean.com)

...then install the plugin?

Can't wait for the inline-topic searching!
-_-
Installation Problem:
When I try accessing the Solr page via ACP, it gives me a 404 error. Any thoughts?

@julian said:

npm install nodebb-plugin-solr

Maybe you should upgrade NodeBB to the latest.

[trevor]

@main It is updated to latest.

[mani]

I have the same problem before, but after update NodeBB and Solr plugin, it's gone. Have you updated all of that?

[trevor]

This is the error I'm getting:

warn: Plugin: /home/c/node_modules/nodebb-plugin-solr is corrupted or invalid. Please check plugin.json for errors.

I disabled all plugins @_@

I noticed theres a version difference in NPM and on Github.

@a_5mith I can't build index and when I search got this error:

@trevor Yes, npm is the latest.

[mani]

@a_5mith I think it's because I didn't install Solr, so I'll install and try again.

[trevor]

Okay apparently it WASN'T updated to latest, lol. The following changes were made that fixed it; https://github.com/NodeBB/NodeBB/commit/7212f95582eb1e828ad6845a1b7f7f4dbb8b9e39

Thanks @main

[mani]

@trevor Thank you too, I just installed Solr by your instruction and make everything works!

[trevor]

Note: Installing and running Solr takes up a good bit of your CPU so if you're using DigitalOcean, I suggest you use the 10$/mo plan instead of the $5/mo.

How does this plugin compare to the DB Search as far as features and accuracy?

[Haowei]

It works fine on our http://nodebb.org.cn
