我是 Solr 的新手。我正在使用 spring 3.x 和 Solr 4.6
下面是我的Schema.xml
<schema name="customer_site_address" version="1.5">

下面是RequestHandler在solrconfig.xml

现在，当我调用/spell一个frgo生成以下查询字符串的城市时。
qt=/spell&spellcheck.q=frgo&spellcheck=true&mm=100%
我得到以下替代方案：（当前结果）
[f r, f r g, fargo, f r g o, farg]
它应该给我：（预期）
[fargo]
wset frgo当我输入时生成以下查询字符串的另一种情况
qt=/spell&spellcheck.q=wset+frgo&spellcheck=true&mm=100%
我得到以下替代方案：（当前结果）
[w s, w s e, west, w s e t, wert, f r, f r g, fargo, f r g o, farg]
它应该给我：（预期）
[West, West Fargo]
我确实应用了通过谷歌找到的一些解决方案，但我认为我在配置时犯了错误。我也尝试过使用solr.KeywordTokenizerFactoryand solr.WhitespaceTokenizerFactoryforindex和queryanalyzer。
请指导我。
编辑：
我删除了下面的过滤器，它在某些时候起作用。
<filter class="solr.EdgeNGramFilterFactory" minGramSize="1" maxGramSize="15" side="front"/>
现在，如果我输入wset frgo生成下面的查询字符串
qt=/spell&spellcheck.q=wset+frgo&spellcheck=true
我得到以下替代方案：（当前结果）
[west, fargo, farg]
它应该给我：（预期）
[west, fargo, west fargo]
仍然West Fargo没有返回。
请指导我
谢谢
