Search

Introduction

Search for a website can be a complex or simple procedure. Utilising Google Search enables a simple snippet of HTML to be placed on the site and Google will do the heavy lifting. However the results are limited to the pages Google already has indexed.

Using software like Elastic Search, enables a programmatic search API for the site. A lot more complex but highly configurable and bespoke.

Creating a JavaScript search for a static site requires the index to be generated in JSON at build time.

Search Elastic Search Directly

$ curl http://localhost:9200/insurance/_search?q="KPMG"

Setup

Structure

Commands

Start Elastic Search

$ sudo rcelasticsearch start

Without the Service Wrapper

Start : ./elasticsearch/bin/elasticsearch -p pidfile
Stop  : kill `cat pidfile`

Check that Elastic Search is Running

$ sudo rcelasticsearch status

Process

In order to be able to do pagination we need to create Elastica_Query object as it's the only one who'd be able to hold 'from' parameter see this Discussion

Install the Service Wrapper

$ curl -L http://github.com/elasticsearch/elasticsearch-servicewrapper/tarball/master | tar -xz

$ mv ~/elasticsearch-elasticsearch-servicewrapper-d47d048/service /usr/local/elasticsearch-0.20.1/bin/

$ rm -Rf ~/elasticsearch-elasticsearch-servicewrapper-d47d048
  • Configuration

    $ sudo nano /usr/local/elasticsearch-0.20.1/bin/service/elasticsearch.conf

  • Setup ElasticSearch as a service:

    $ ./usr/local/elasticsearch-0.20.1/bin/service/elasticsearch start stop restart
  • Set up rcelasticsearch as a shortcut to the service wrapper:

    $ sudo bash /usr/local/elasticsearch-0.20.1/bin/service/elasticsearch install $ sudo ln -s readlink -f /usr/local/elasticsearch-0.20.1/bin/service/elasticsearch /usr/local/bin/rcelasticsearch
