Elias, I'm assuming you have one composite field that looks like so: __ where is ISO8601 basic format down to an hour resolution. If this is the case then you _cannot_ perform an efficient, nor correct (without doing extra work in your application), query on the portion of the field. To use

Riak Search Performance: Ranges vs Wildcards

2012-01-06 Thread Elias Levy
I was wondering whether some of the Basho folk may have some wise words about when to choose between ranges and wildcards when using Riak Search. I've noticed in our systems that using wildcards will often give more performant results than using ranges, at least for our data and some of the indexe

Hi Guys, Its a great work to make search with erlang-lucene family. I wonder is there any benchmarks withs 10M+ web documents ? We have subseconds performance with 12M docs on SOLR. But maintaining keeping the system alive sometimes a nightmare... Can we solve our problems with riak_search ?
