未定義字段* solrj地理位置查詢

Question

我試圖在我的solrj查詢中使用位置geodist函數。 我的solr查詢是：-

q=*:*&sfield=latlng_coordinate&pt=70.00,80.000&sort=geodist() asc&fl=_dist_:geodist()&fl=name,id&fl=name,id

當我從瀏覽器中命中此查詢時，此查詢工作正常，但一旦嘗試從Java代碼中命中此查詢，它將引發以下異常：-

嘗試在過去4-5個小時內進行調試，但找不到解決方案。

Answer 1

我想請求網址中有問題。

查看move2gathercollection，我發現查詢未完全編碼。 如果所有查詢q=*:*均已編碼，則應為q=*%3A*

因此，假設q參數已正確編碼，則問題在於其余URL可能在調用之前被編碼了兩次。

只是要清楚一點，當我查看solr日志時，請求已被解碼，因此您可以讀取所有參數。 在您的日志中：

INFO: [move2gathercollection] webapp=/solr path=/select params={q=*:*%26sfield%3Dlatlng_coordinate%26pt%3D70.00,80.000%26sort%3Dgeodist()+asc%26fl%3D_dist_:geodist()%26fl%3Dname,id&fl=name,id&wt=javabin&version=2} status=400 QTime=3 

我只看到請求的第一部分是可讀的q=*:* ，其余的URL %26sfield%3Dlatlng_coordinate%26pt%3D70.00,80.000%26sort%3Dgeodist()+asc%26fl%3D_dist_:geodist()%26fl%3Dname編碼%26sfield%3Dlatlng_coordinate%26pt%3D70.00,80.000%26sort%3Dgeodist()+asc%26fl%3D_dist_:geodist()%26fl%3Dname ，這對我來說很奇怪。

我想將q:之后的整個字符串讀為以*開頭的字段的名稱。
