Added elasticSearch to the project... but still on testing.

WebSystem using Elastic Search

-> with nodejs API to comunicate with the elasticsearch

Instalation of the websystem as a archlinux (general instructions, also applies for other linux alike systems)

install npm pacman -S npm

install nodeversion manager to install node 6.11.0. Should work with version above too for more info about the node version manager: github.com/tj/n npm install -g n

install node 6.11.0 n 6.11.0

check if version was installed by typing 'n' at your terminal n

Running the websystem

Go to the folder elastic_node cd ./Siri-Law-Br/elastic_node

Run the server node index.js

server will start at the port localhost:8081 as default now just open the address at your browser (localhost:8081). When typing anything at the search field, make sure that u have internet connection and your local elasticsearch is running.

Running the elastic search in the same server as the websystem

Pre-requisite: java 8 runtime enviroment (jre8-openjdk) Download elastic search and unzip the archive anywhere. Currently using 5.0.0

• https://www.elastic.co/downloads/elasticsearch
• https://www.elastic.co/downloads/past-releases/elasticsearch-5-0-0

Configure the elastic search to acc request from the same server. Go to config folder, open elasticsearch.yml. makesure the network.host has 'localhost' as value and 'http.port' has a different port(9200 for example) from the websystem (8081). Now add the last three lines that will make elasticsearch to receive and send request from the same server.

Add at the end of file.

http.cors.enabled: true
http.cors.allow-origin: "/.*/"
http.cors.allow-headers: "X-Requested-With, Content-Type, Content-Length, Authorization, Access-Control-Allow-Origin"

your file will look like this:

network.host: localhost
http.port: 9200
...
http.cors.enabled: true
http.cors.allow-origin: "/.*/"
http.cors.allow-headers: "X-Requested-With, Content-Type, Content-Length, Authorization, Access-Control-Allow-Origin"

Enter the folder and execute elasticsearch

./bin/elasticsearch 

If you dont have the elastic search indexed with cdc already. Check this link below. It has the default structure to make the web system works. https://github.com/dnovaes/Siri-Law-Br/blob/master/elastic_node/indexing_es.md
