Ingest processor doing language detection for fields

Elasticsearch Langdetect Ingest Processor

Uses the langdetect plugin to try to find out the language used in a field.

Usage

PUT _ingest/pipeline/langdetect-pipeline
{
  "description": "A pipeline to do whatever",
  "processors": [
    {
      "langdetect" : {
        "field" : "my_field"
        "target_field" : "language"
      }
    }
  ]
}

PUT /my-index/my-type/1?pipeline_id=langdetect-pipeline
{
  "my_field" : "This is hopefully an english text, that will be detected."
}

GET /my-index/my-type/1
{
  "my_field" : "This is hopefully an english text, that will be detected.",
  "language": "en"
}

Configuration

Parameter Use
field Field name of where to read the content from
target_field Field name to write the language to
max_length Max length of of characters to read, defaults to 10kb, requires a byte size value, like 1mb

Setup

In order to install this plugin, you need to create a zip distribution first by running

gradle clean check

This will produce a zip file in build/distributions.

After building the zip file, you can install it like this

bin/plugin install file:///path/to/ingest-langdetect/build/distribution/ingest-langdetect-0.0.1-SNAPSHOT.zip

Side notes

In order to cope with the security manager, a special factory is used to load the languages from the classpath. You can check out the SecureDetectorFactory class. This implementation also does not use jsonic to prevent the use of reflection when loading the languages.
