Solr與Django一起工作只能找到精確匹配

我在索引頁上有一個django應用程序和一個搜索欄。我安裝乾草堆和solr。我輸入蟒蛇manage.py build_solr_schema並獲得粘貼以下XML示例/ Solr的/ conf目錄/ schema.xml中Solr與Django一起工作只能找到精確匹配

我有一個名爲評爲「foorightfoo」的對象。當我搜索「富」沒有出現，但當我搜索「foorightfoo」答案出現。同時，當我從太陽能管理面板檢查，同樣的情況繼續... 我的搜索僅適用於完全match.Any想法？

其實我通過操縱我的schema.xml中的最後一節像

- <field name="text" type="text_en" indexed="true" stored="true" multiValued="false" /> 

+ <field name="text" type="ngram" indexed="true" stored="true" multiValued="false" />

固定的問題用ngram改變搜索字段的類型做伎倆

您需要在最後追加一個外卡*，所以查詢像

q=title:foo*

仍然是一樣的。http://127.0.0.1:8000/?q=foorightfoo是好的，但http://127.0.0.1:8000/?q=foo*空了 – tunaktunak 2013-02-23 10:11:19

肛門然後ysis工具應該可以幫助你自己調試。查看'foorightfoo'在索引時產生的標記。對於默認的Solr 4.0示例安裝，它位於http：// localhost：8983/solr /＃/ collection1/analysis。將它映射爲您的路徑並嘗試 – arun 2013-02-23 18:50:30
