Program solving the recipe search problem.

• Search results should be relevant, e.g. a search for broccoli stilton soup should return at least broccoli stilton soup.

• Searches should complete quickly so users are not kept waiting – this tool needs to serve many users so lower latency will mean we can serve more concurrent searches - ideally searches will take < 10ms.

• Ideally the results will be sorted so that the most relevant result is first in the result list.

• The name of each file is considered the id of the recipe.

• Returning relevant results is fairly open ended and subjective, so there is a lot of room for increasing sophistication.

• Performance / Resource utilisation is another area where you can apply more sophistication to the solution.

• Degree to which the solution is generalized without loss of clarity is another.

• Be reasonable in your use of libraries or existing search tools – In this test we really do want you to reinvent the wheel as far as the core problem is concerned!

• Just using grep will not win you many points. Feel free to use established techniques and algorithms, in fact this is encouraged.

Copy profile.clj.example as profile.clj so the configuration suits your needs. Without profiles.clj default configuration from project.clj will be used (api on 3001).
