Riak 中的多个查询
Multiple queries in Riak
我正在通过 HTTP API 查询我的 Riak 数据库，如下所示：
/select?q=+build:2702168+hypervisors:500&q.op=and&wt=json&sort=tstart_int%20desc"
但是除第一个参数之外的所有其他查询参数都将被忽略。所以在这种情况下，它 returns 所有满足 build:2702168 的条目，但忽略 hypervisors:500.
This piece of documentation，虽然很旧，但表明您可以进行常规的 solr 多查询：
The following example return documents containing the words “red” and
“blue” but not “yellow”.
red AND blue AND NOT yellow
The required ( + ) operator can be used in
place of “AND”, and the prohibited ( - ) operator can be used in place
of “AND NOT”. For example, the query above can be rewritten as:
+red +blue -yellow
但是，我在最新的 Riak 文档中找不到相同的信息。还有其他方法吗？
这似乎是一个很老的错误。 According to Basho's Ryan Zezeski:
At one time I fixed it but it had to be reverted because it broke
rolling upgrade 1. It has languished ever since. To work around
explicitly put AND in the query. E.g.
q=nickname:Ring%20AND%20breed:Shepherd
正如他所说，改为这样做：
/select?q=build:2702168%20AND%20hypervisors:500&wt=json&sort=tstart_int%20desc
已解决问题。
