solr：功能使用问题

解决[问题]中描述的问题：Solr: where to store additional information?我写了一个函数termcnt（fieldname），它只计算文档中有关指定fieldname的特定术语 .
在"Solr/Lucene Statement"中使用solr管理页面（http://localhost:8080/admin/form.jsp）我查询：

fq={!frange l=3 u=1000}termcnt(wc_text)

并得到一个错误：

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: "}" ... ).

我的错在哪里？

谢谢

附：当我在等待时：

_val_:"termcnt(wc_text)"

我的功能正常...

P.P.S甚至与sum func我有相同的结果:(

fq={!frange l=3 u=1000}sum(2,3)

solr 3.2.0
lucene 3.2.0
