实时分布式搜索引擎比较（senseidb、Solr、elasticsearch）
三、Some example usages:
Sphinx: craigslist.org
Solr: Cnet,
Netflix, digg.com
Elasticsearch: Foursquare, Github
Options for Full Text Search Before I dig into the steps required for ElasticSearch, I will mention some other options for implementing full-text in your solution:
Sphinx – used by craigslist Solr – used by CNet, Netflix, digg.com
ElasticSearch – used by Foursquare, Github(source: StackOverflow, thanks Tommy for highlighting use cases) given that I use PostgreSQL, I could also just use FTS in PostgreSQL
In the .NET. world, the above solutions have got .NET connectors. For SpinxConnector.NET – very good! Unfortunately it costs EUR199 for a single dev license. If it were free, I probably would have used this one. SolrNET – is an active GitHub project with quite a few contributors.
If you are looking to implement Solr in .NET, this is probably the way to go. NEST for ElasticSearch – this is the official high level ElasticSearch client for .NET. I chose to go with this option & there are some code examples below on how I implemented it. .
