SearchJsonData

Minimum requirements:

A search for Lisp Common should match a programming language named "Common Lisp"
Your solution will be tested on a server running Ubuntu, Ruby 2.1 and Rails 4.2

Meriting:

Writing code with reusability in mind
Search match precision
Search results ordered by relevance
Support for exact matches, eg. Interpreted "Thomas Eugene", which should match "BASIC", but not "Haskell"
Match in different fields, eg. Scripting Microsoft should return all scripting languages designed by "Microsoft"
Support for negative searches, eg. john -array, which should match "BASIC", "Haskell", "Lisp" and "S-Lang", but not "Chapel", "Fortran" or "S".

Installation

Add this line to your application's Gemfile:

gem 'search_json_data'

And then execute:

$ bundle

Or install it yourself as:

$ gem install search_json_data

Usage

After install the gem include in your code this require

require 'search_json_data'

Then you can instanciate the object

# the argument is the path to the json file
@data = DataArray.new /path/to/file/data.json

    # then you can search words in the collection
    #
    # @param words [String] words to search, when are quoted must match exactly
    # @param field [String] the name of the field, is nil by default in this case search in all fields
    # @param condition [String, nil] the condition to search, by default nil to add results to the before search,
    # otherwise AND return only the results in both searches
    # @param precision [Boolean, false] false by default, true is case sensitive
    # @return [Array] collection of matching results
@data.search_by "Scripting Microsoft"
