ElasticSearch - How to install? PDF?

[cappuccino]

Hello

Does anybody know, is it possible to search text in PDFs or other attachments with ElasticSearch?

And how I have to install ElasticSearch? I've download Elasticsearch (https://www.elastic.co/downloads/elasticsearch). But in which folder I have to unzip the files? And how I do install this?

Thanks for your help.

The easiest way to install is to paste: ElasticSearch into Modules > Site > Add New > Module Class Name

I don't know much about the Elastic Search module. Another option which I know handles searching PDF files is: http://modules.processwire.com/modules/indexer/

Well, it's not THAT easy. Check here: https://www.digitalocean.com/community/tutorials/how-to-install-and-configure-elasticsearch-on-ubuntu-14-04

I suggest you read about the way ElasticSearch works to understand what is possible and what is not, and how to adapt it to your needs. It seems easy, but it a mighty thing and as such can easily cause more trouble than it's worth.

I went down the Elasticsearch rabbit hole and found that there is quite a learning curve. The PW module by Jonathan Dart is a great starting point but think of it as a Hello World demo. To really make effective use of Elasticsearch you need to learn about "mapping" info and indexing your data and you need to get a feel for the way the query language works. It's a big weird tool but it's worth it to get things like stemming.
