Foundation: Learn and Play with Elasticsearch
I have posted about several of the articles here but missed posting about the homepage for this site.
Take a close look at Play. It offers you the opportunity to alter documents and search settings, online experimentation I would call it, with ElasticSearch.
The idea of simple, interactive play with search software is a good one.
I wonder how that would translate into an interface for the same thing for topic maps?
The immediacy of feedback along with a non-complex interface would be selling points to me.
You will also find some twenty-five articles (as of today) ranging from beginner to more advanced topics on ElasticSearch.
