Added entry for Solr for newbies

[hectorcorrea]

What does this PR do?

Adds entry for book "Solr for newbies"

For resources

Book "Solr for newbies"

Description

A book on how to get started with Apache Solr.

Why is this valuable (or not)?

I thought the content is relevant to programmers. There are a couple of entries already for ElasticSearch but I didn't see anything for Solr.

How do we know it's really free?

I wrote it and licensed under the Creative Commons Attribution 4.0 International License.

For book lists, is it a book? For course lists, is it a course? etc.

It's the materials for a workshop, in book format.

This is a great addition!
We've been trying to avoid single-item categories. Are there no other free books on Solr? Would this be better under Java? Should we have a category for things like Solr and Elasticsearch? (on the list of things to do is moving MySQL and Postgres into an SQL category.)

[hectorcorrea]

I think grouping Solr and ElasticSearch books into a single category ("Search Tools/DBs/Engines"?) would be a good idea. I didn't feel like I had enough authority/knowledge on how the organization was setup to make that kind of change.

[eshellman]

Let's create "Search" under "Language Agnostic". We're looking at ways to improve usability of the too-big books page and I think we'll rename "Language Agnostic" to something like "Topics" or "Subjects". Appreciate your help on this.

Bump review. Then move it to Language Agnostic > Search?

Merge ElasticSearch and Solr resources into same section: Search Engines
