我需要查询产品数据库，查询可以包含正斜杠（例如“ 30/20”），但是它总是将查询分为两部分，例如 _text：30和_text：20。
我试图用反斜杠（例如“ 30/20”）转义正斜杠，或者将encodeURI用作“ 30％2F20”，但是它也不起作用。
我应该在数据库中编码/替换正斜杠吗？
我尝试在查询字段中使用（Solr Query not parsing forward slash）后面的引号，例如“ 5/12”，如果数据库中包含“ 12.5 / 12”，则该行不起作用。
有人遇到了这个问题吗？ 预先感谢！

上拆分的其他标记器，例如the WhitespaceTokenizer。这样，/将被保留为一个单一令牌。
如果您仍然需要支持查询5/12的用户以提供匹配，则可以由原始字段类型提供服务。如果您还需要支持通过完整令牌的子集进行查询（例如，当值为5 12时是5/12），请使用NGramFilter将令牌进一步拆分为覆盖每个组合的子令牌（{{1 }}，12.5/12，1等）。
