Elasticlunr

Test

Elasticlunr is a small, full-text search library for use in the Elixir environment. It indexes JSON documents and provides a friendly search interface to retrieve documents.

Why

The library is built for web applications that do not require the deployment complexities of popular search engines while taking advantage of the Beam capabilities.

Imagine how much is gained when the search functionality of your application resides in the same environment (Beam VM) as your business logic; search resolves faster, the number of services (Elasticsearch, Solr, and so on) to monitor reduces.

Installation

The library can be installed by adding elasticlunr to your list of dependencies in mix.exs:

def deps do
  [
    {:elasticlunr, "~> 0.5"}
  ]
end

Documentation can be found at hexdocs.pm. See blog post Introduction to Elasticlunr and Livebook for examples.

Features

  1. Query-Time Boosting, you don't need to set up boosting weight in the index building procedure, Query-Time Boosting makes it more flexible so you could try different boosting schemes
  2. More Rational Scoring Mechanism, Elasticlunr uses a similar scoring mechanism as Elasticsearch, and also this scoring mechanism is used by Lucene
  3. Field-Search, you can choose which field to index and which field to search
  4. Boolean Model, you can set which field to search and the boolean model for each query token, such as "OR" and "AND"
  5. Combined Boolean Model, TF/IDF Model, and the Vector Space Model make the results ranking more reliable.

Token Expansion

Sometimes users want to expand a query token to increase RECALL. For example, user query token is "micro", and assume "microwave" and "microscope" are in the index, if the user chooses to expand the query token "micro" to increase RECALL, both "microwave" and "microscope" will be returned and search in the index. The query results from expanded tokens are penalized because they are not the same as the query token.
