Goal

In this task you are requested to implement a simple free text search engine service. We are looking for a working solution with a clean design. Requirements The engine should at least supply the following capabilities: *Index – an ability to add a new document/s that later can be surfaced during search. *search(query) – an ability to provide a query and receive as output a ranked list of documents based on their similarity to the query.

Implementation Details

• Provide a generic option for using different similarity algorithms, and implement two options yourself
• Provide a generic option for using different tokenization methods, and implement two options yourself
• Notice, the system can be used by numerous users in parallel.

Example

In this example the similarity function is number of shared tokens, and the tokenization is done by splitting the string by spaces:

curl -d "the cow says moo" -X POST http://127.0.0.1:5000/index
curl -d "the cat and the hat" -X POST http://127.0.0.1:5000/index
curl -d " the dish ran away with the spoon" -X POST http://127.0.0.1:5000/index
curl -d " a cat ran away" -X POST http://127.0.0.1:5000/se

Usage

Build: mvn clean install

Access:

• http://localhost:8080/list
• http://localhost:8080/index
• http://localhost:8080/search
