Kelastika

Elastika writen in Kotlin

Installation:

Install and start Elastic Search

➜ brew install elasticsearch
➜ elasticsearch

Import project into IntelliJ IDEA. If you want to run the project just do type CMD + ALT + R, RIGHT, EDIT and check that the following fields are correct:

  • Main class: com.irontec.KelastikaKt
  • Program arguments (you can change them): -p 9200 -i irontecdocs -t irondocs --file test.pdf
  • Working directory: your_path/kelastika/test
  • Apply
  • Run

You can also generate a .jar file. Just go to Module - Artifacts - Add (+) and select JAR - From modules with dependencies - Select Kelastika + Ok Then, generate the JAR just by clicking in Build + Build artifacts. This will generate a out folder with the jar file, move that jar file to your_path/kelastika/test and you're ready to go.

How it works:

  • The program will extract the contents and metadata from the specified file
  • It will check if the especified ìndex and mappingexist and if not it will try to create them.
  • If everything goes fine, it will post the data to the Elastic Search instance.
