Solr 搜索多值字段
我有一个如下所示的多值字段：
<arr name="some_name">
<str>a-value-1 a-value-2 ....a-value-n</str>
<str>b-value-1 b-value-2 ....b-value-m</str>
</arr>
其中 n 和 m 可以任意大（假设每个
我将如何搜索以使结果仅包含所有搜索参数都包含在同一
例如，如果文档 A 具有以下内容：
<arr name="some_name">
<str>london foo-1 foo-2 ...foo-k 2012 foo-k+1 foo-k+2 ...foo-k+n</str>
<str>beijing bar-1 bar-2 ....bar-j 2008 bar-j+1 bar-j+2 ....bar-j+m</str>
</arr>
在搜索单词 london AND 2008 时，结果中不会包含文档 A 的查询是什么？
如果我尝试这样的 some_name:("london AND 2008"~n)，我不知道 n 的值是多少。
I have a multivalued field that appears like this :
<arr name="some_name">
<str>a-value-1 a-value-2 ....a-value-n</str>
<str>b-value-1 b-value-2 ....b-value-m</str>
</arr>
where n and m could be arbitrarily large(assume values in each <str> come from a paragraph in a page or something).
How would I search so that the result contains only the documents where all search parameters are contained in the same <str> entity(That is without generating any false positive)?
For instance if the document A has this :
<arr name="some_name">
<str>london foo-1 foo-2 ...foo-k 2012 foo-k+1 foo-k+2 ...foo-k+n</str>
<str>beijing bar-1 bar-2 ....bar-j 2008 bar-j+1 bar-j+2 ....bar-j+m</str>
</arr>
what will be the query that would not include document A in the result when searching for the words london AND 2008?
If I were to try something like this some_name:("london AND 2008"~n), I don't know what the value of n would be.

考虑使用高positionIncrementGap，这将有助于分离多值标记并跨不同多值条目进行交叉匹配。
然而，即使这也不是一个万无一失的解决方案。
Consider using a high positionIncrementGap, which will help to separate the multivalued tokens and cross matching across different multivalued entries.
However, even this wont be a foolproof solution.
