问题描述
正斜杠/"是 solr 字段名称中的保留字符吗?
Is the forward slash "/" a reserved character in solr field names?
我在编写 solr 排序查询时遇到问题，该查询将解析包含正斜杠/"的字段
I'm having trouble writing a solr sort query which will parse for fields containing a forward slash "/"
对我的 solr 服务器进行 http 查询时:
When making an http query to my solr server:
q=*&sort=normal+desc
会工作，但是
q=*&sort=with/slash+desc
q=*&sort=with%2Fslash+desc
两者都失败说不能在多值字段上使用 FieldCache:with"
Both fail say "can not use FieldCache on multivalued field: with"
每个 solr 文档包含两个 int 字段normal"和with/slash".使用我的 solr 架构索引字段
Each solr document contains two int fields "normal", and "with/slash". With my solr schema indexing the fields as so
...
<field name="normal" type="int" indexed="true" stored="true" required="false" />
<field name="with/slash" type="int" indexed="true" stored="true" required="false" />
...
我需要用什么特殊的方式在 solr 中编码正斜杠吗?或者我可以使用任何其他分隔符吗?我已经在使用-"和."用于其他目的.
Is there any special way I need to encode forward slashes in solr? Or are there any other delimiter characters I can use? I'm already using '-' and "." for other purposes.
推荐答案
我也遇到了同样的问题，经过实验发现如果字段名有斜杠，必须转义在 Solr 查询中带有反斜杠(但请注意，您不必在字段列表参数中执行此操作，因此输入了查找包含 my_value 的 /my/field/name 的搜索在q"字段中为:
I just came across the same problem, and after some experimentation found that if you have a forward-slash in the field name, you must escape it with a backslash in the Solr query (but note that you do not have to do this in the field list parameter, so a search looking for /my/field/name containing my_value is entered in the "q" field as:
/my/field/name:my_value
我还没有尝试过排序字段，但试试这个并告诉我们:)
I haven't tried the sort field, but try this and let us know :)
这是 Solr 4.0.0 alpha 版.
This is on Solr 4.0.0 alpha.
