solr - solr 中的求和函数

Question

嗨，我正在尝试 solr 中的 sum 函数

val :"sum(kcmeta/书签/计数,10.00)"

给出错误：

<lst name="error">
  <str name="msg">undefined field: "kcmeta"</str>
  <int name="code">400</int>
</lst>

我的字段名称是“kcmeta/bookmark/count”

请建议如何解决这个问题。

Try to escape the special char you have in the name like this:

val:"sum(kcmeta\/bookmark\/count,10.00)"

This should not happen but it seems there is a bug, so the escaping should work around the bug: issues.apache.org/jira/browse/SOLR-3996
