我正在开发一个需要我第一次使用Solr的应用程序。我设置了它,索引正确的数据,并按照我的意愿查询,但我不能似乎让拼写检查组件正常工作。无论我查询什么,拼写检查器都不会返回任何建议。我已经包含了solrconfig和schema.xml的相关部分。
schema.xml中
<fieldType name="textSpell" class="solr.TextField" positionIncrementGap="100" omitNorms="true">
<analyzer type="index">
<charFilter class="solr.HTMLStripCharFilterFactory"/>
<tokenizer class="solr.StandardTokenizerFactory"/>
<filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt"/>
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.StandardFilterFactory"/>
</analyzer>
<analyzer type="query">
<tokenizer class="solr.StandardTokenizerFactory"/>
<filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" ignoreCase="true" expand="true"/>
<filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt"/>
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.StandardFilterFactory"/>
</analyzer>
</fieldType>
<!-- CUT -->
<field name="spell" type="textSpell" indexed="true" stored="true" />
solrconfig.xml中

当我转到http://localhost:8983/solr/select/?q=query&spellcheck.build=true
然后查看/ path / to / my / spell / index中生成的文件时,有一个segments.gen和一个segments_1,两者都只包含几个字节的二进制文件数据。然后,当我输入查询并将&spellcheck=true
附加到查询字符串时,无论我的查询是什么,我都会收到 no 建议:
<lst name="spellcheck">
<lst name="suggestions"/>
</lst>
知道这里发生了什么吗?

我有一个非常类似的问题,我无法解决。有人在我的问题上发布了一个可以帮助你的详细答案:
答案 1 :(得分:2)
我不久前最终解决了这个问题,但对我的回忆,问题是我使用多个<copyField/>
指令将数据复制到“spell”字段,但我没有设置{{1在那个领域。当我将拼写检查字段变为多值时,它就像一个魅力!
