Elasticsearch


elasticsearch is schema less, just toss it a typed JSON document and it will automatically index it. Types such as numbers and dates are automatically detected and treated accordingly.

But, as we all know, Search Engines are quite sophisticated. Fields in documents can have boost levels that affect scoring, analyzers can be used to control how text gets tokenized into terms, certain fields should not be analyzed at all, and so on… . elasticsearch allows you to completely control how a JSON document gets mapped into the search engine on a per type and per index level.
