I had a chance to benchmark two major searching engines, ElasticSearch and Apache Solr.
My first impression was that ES was easy to understand and build an environment while Solr was flexible enough to suit to any use cases.
Regarding performance, it depends on the use case of course, in my case, ES was faster in general search such as keywords AND/OR query. In faceting, both engine showed similar performance. Since query syntax is completely different between them, learning cost(eg.time) is considerable..
Peach parfait! It was a great refreshment on a humid-hot day!!
Ice hole fishing on a frozen lake at Mt Akagi. Too cold and no luck. :<
The last two photos compare the scenic difference. See? it’s frozen!!
What is your favorite winter activity?
Now I’m playing with Hadoop, an open source big data solution, struggling with the lack of concrete information.
It’s wintertime in Tokyo, but spring has come here, Chiba prefecture, next to Tokyo. Flower picking is a popular activity. 🙂
It was an extremely hot Saturday. I really enjoyed showshoeing at Kirifuri Highland Park in Nikko. http://www.kirifuri-kogen.jp/english/
