solr：函数使用问题
continue
to solve a problem described at [question]: Solr: where to store additional information?
i wrote a function termcnt(fieldname) which just count specific terms in document regarding specified fieldname.
Using solr admin page (http://localhost:8080/admin/form.jsp) in "Solr/Lucene Statement" I queried:
fq={!frange l=3 u=1000}termcnt(wc_text)
and got an error:
type Status report
message org.apache.lucene.queryParser.ParseException: Cannot parse 'fq={!frange l=3 u=1000}termcnt(wc_text)': Encountered " <RANGEEX_GOOP> "u=1000 "" at line 1, column 16. Was expecting: "}" ...
description The request sent by the client was syntactically incorrect (org.apache.lucene.queryParser.ParseException: Cannot parse 'fq={!frange l=3 u=1000}termcnt(wc_text)': Encountered " <RANGEEX_GOOP> "u=1000 "" at line 1, column 16. Was expecting: "}" ... ).
where is my mistake?
thank you
P.S. when I'm queering:
_val_:"termcnt(wc_text)"
my function is working properly...
P.P.S even with sum func i have the same results :(
fq={!frange l=3 u=1000}sum(2,3)
solr 3.2.0
lucene 3.2.0
(from maven repository)

我相信自从编写此内容以来界面已经发生了一些变化 - 但您的查询
似乎编写正确。您可能会尝试对其进行 url 编码，例如
但我有一种感觉，这个问题仅通过较新版本的 Solr 和管理面板即可解决。
I believe the interface has changed somewhat since this was written--but your query
seems to be written correctly. You might try to url encode it, like
But I have a feeling this issue is solved just from newer versions of Solr and the admin panel.
