Solr查询未解析正斜杠 [英] Solr Query not parsing forward slash

问题描述

solr字段名称中的斜杠"/"是保留字符吗?

我在编写Solr排序查询时遇到麻烦，该查询将解析包含正斜杠"/"的字段

对我的Solr服务器进行http查询时:

q=*&sort=normal+desc

可以，但是

q=*&sort=with/slash+desc
q=*&sort=with%2Fslash+desc

均失败的原因是不能在多值字段上使用FieldCache:"

每个solr文档都包含两个int字段"normal"和"with/slash".用我的Solr模式将字段编入索引

...
<field name="normal" type="int"   indexed="true" stored="true" required="false" />
<field name="with/slash" type="int"   indexed="true" stored="true" required="false" />
...

我有什么特殊的方法可以在solr中对正斜杠进行编码吗?还是我可以使用其他定界符?我已经在使用'-'和.".用于其他目的.

解决方案

我遇到了同样的问题，经过一些实验后发现，如果字段名中有正斜杠，则必须将其转义在Solr查询中使用反斜杠(但请注意，您不必在字段列表参数中执行此操作，因此，在"q"字段中输入查找包含my_value的/my/field/name的搜索为:

\/my\/field\/name:my_value

我还没有尝试排序字段，但是尝试一下，让我们知道:)

这是在Solr 4.0.0 alpha上.

Is the forward slash "/" a reserved character in solr field names?

I'm having trouble writing a solr sort query which will parse for fields containing a forward slash "/"

When making an http query to my solr server:

q=*&sort=normal+desc

Will work but

q=*&sort=with/slash+desc
q=*&sort=with%2Fslash+desc

Both fail say "can not use FieldCache on multivalued field: with"

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" />
...

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.

解决方案

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

I haven't tried the sort field, but try this and let us know :)

This is on Solr 4.0.0 alpha.
