solr：函數使用問題

Question

解決在[question]中描述的問題：Solr: where to store additional information? 我寫了一個函數termcnt（fieldname），它只是計算關於指定字段名的文檔中的特定術語。
中的 「Solr/Lucene的聲明」 使用Solr管理頁面（http://localhost:8080/admin/form.jsp）我問：

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

，並得到了一個錯誤：

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: "}" ...). 

哪裏是我的錯？

謝謝

附：當我queering：

_val_:"termcnt(wc_text)" 

我的功能是否正常工作......

PPS甚至和FUNC我有同樣的結果:(

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

的Solr 3.2.0
lucene的3.2.0
（來自行家庫）

堆棧跟蹤（的要求）：

Answer 1

我相信接口已經有所改變，因爲這是寫 - 但查詢

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

似乎是正確寫入。您可以嘗試URL編碼它，就像

fq=%7B!frange+l%3D3+u%3D1000%7Dsum(2%2C3) 

但我有一種感覺，這個問題只是從Solr中的較新版本和管理面板解決。
