[英]Special characters in Solr filter fq
I'm trying to filter with fq
for fields having special characters, particularly parentheses. 我正在尝试使用fq
过滤具有特殊字符的字段,尤其是括号。 For example, given the document: 例如,给定文件:
<result name="response" numFound="1" start="0">
<doc>
<arr name="town_snc">
<str>Hartford (Connecticut)</str>
</arr>
</doc>
</result>
I want to do eg ?fq:town_snc=Hartford (Connecticut)
我想做什么?fq:town_snc=Hartford (Connecticut)
I'm not getting any results; 我没有得到任何结果; I presume that the parentheses need to be escaped, but I was not able to find the escaping method. 我认为括号需要转义,但我无法找到转义方法。
Thank you! 谢谢!
Using the "field" qparser allows you to not have to do any escaping: 使用“field”qparser可以让你不必进行任何转义:
fq={!field f=town_snc}Hartford (Connecticut)
Or you can use the normal lucene query parser and use double quotes (but then you must still escape some things like quotes) 或者您可以使用普通的lucene查询解析器并使用双引号(但是您仍然必须转义某些内容,如引号)
fq=town_snc:"Hartford (Connecticut)"
Or you could use backslash escaping too (just remember to also escape the space). 或者你也可以使用反斜杠转义(只记得也逃避空间)。
