我无法让ngrams工作。这是我的schema.xml：
<!-- partial-match text search -->
<fieldType class="solr.TextField" name="autosuggest" positionIncrementGap="100">
<analyzer type="index">
<tokenizer class="solr.LowerCaseTokenizerFactory"/>
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.EdgeNGramFilterFactory" minGramSize="1" maxGramSize="25" side="front"/>
</analyzer>
<analyzer type="query">
<tokenizer class="solr.LowerCaseTokenizerFactory"/>
<filter class="solr.LowerCaseFilterFactory"/>
</analyzer>
</fieldType>
<!-- partial-match text search -->
<dynamicField name="*_autosuggest" stored="false" type="autosuggest" multiValued="true" indexed="true"/>
<dynamicField name="*_autosuggests" stored="true" type="autosuggest" multiValued="true" indexed="true"/>
可搜索阻止
searchable do
integer :id, :multiple => true
text :username_lower, as: :username_lower_autosuggest
end
但是当我用捆绑exec rake sunspot：solr：reindex 重新索引此代码时，它会给我一个错误，如下所示
Error - RSolr::Error::Http - 500 Internal Server Error - retrying...
Error - RSolr::Error::Http - 500 Internal Server Error - ignoring...

我无法追踪问题，因为我也在关注太阳黑子文档。
请提出一个正确的方向，因为我从最近1天起被吸收了
