Solr 通配符搜索问题
我在 solr 搜索中遇到问题...通配符搜索似乎工作正常，但当我尝试在另一个单词中查找术语时出现问题...例如：“rtebiggestBug”，当我搜索 Maximum ，它不会给出任何结果。我在 schema.xml 文件中添加了以下条目
<fieldType name="text" class="solr.TextField" positionIncrementGap="100">
<analyzer type="index">
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<!-- in this example, we will only use synonyms at query time
<filter class="solr.SynonymFilterFactory" synonyms="index_synonyms.txt" ignoreCase="true" expand="false"/>
-->
<filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt"/>
<!-- <filter class="solr.WordDelimiterFilterFactory" generateWordParts="1" generateNumberParts="1" catenateWords="1" catenateNumbers="1" catenateAll="0" splitOnCaseChange="1"/>-->
<filter class="solr.LowerCaseFilterFactory"/>
<!-- <filter class="solr.EnglishPorterFilterFactory" protected="protwords.txt"/> -->
<filter class="solr.RemoveDuplicatesTokenFilterFactory"/>
<filter class="solr.EdgeNGramFilterFactory" minGramSize="1" maxGramSize="50" preserveOriginal="1"/>
</analyzer>
<analyzer type="query">
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" ignoreCase="true" expand="true"/>
<filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt"/>
<!-- <filter class="solr.WordDelimiterFilterFactory" generateWordParts="1" generateNumberParts="1" catenateWords="0" catenateNumbers="0" catenateAll="0" splitOnCaseChange="1"/>-->
<filter class="solr.LowerCaseFilterFactory"/>
<!-- <filter class="solr.EnglishPorterFilterFactory" protected="protwords.txt"/>-->
<filter class="solr.RemoveDuplicatesTokenFilterFactory"/>
</analyzer>
</fieldType>
另一个问题是，它在单词末尾找不到字符串。示例：我搜索“bug”，发现了 bug，而不是“samplebug”一词。
如果您能在这个问题上帮助我，那将非常有帮助。
提前致谢。
I am facing an issue in the solr search....The wild card search seems to be working fine but there are issues when i am trying to find terms within another word.....For example: "rtebiggestBug", when i search for biggest , it doesn't give any results.I have the following entries made in the schema.xml file
<fieldType name="text" class="solr.TextField" positionIncrementGap="100">
<analyzer type="index">
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<!-- in this example, we will only use synonyms at query time
<filter class="solr.SynonymFilterFactory" synonyms="index_synonyms.txt" ignoreCase="true" expand="false"/>
-->
<filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt"/>
<!-- <filter class="solr.WordDelimiterFilterFactory" generateWordParts="1" generateNumberParts="1" catenateWords="1" catenateNumbers="1" catenateAll="0" splitOnCaseChange="1"/>-->
<filter class="solr.LowerCaseFilterFactory"/>
<!-- <filter class="solr.EnglishPorterFilterFactory" protected="protwords.txt"/> -->
<filter class="solr.RemoveDuplicatesTokenFilterFactory"/>
<filter class="solr.EdgeNGramFilterFactory" minGramSize="1" maxGramSize="50" preserveOriginal="1"/>
</analyzer>
<analyzer type="query">
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" ignoreCase="true" expand="true"/>
<filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt"/>
<!-- <filter class="solr.WordDelimiterFilterFactory" generateWordParts="1" generateNumberParts="1" catenateWords="0" catenateNumbers="0" catenateAll="0" splitOnCaseChange="1"/>-->
<filter class="solr.LowerCaseFilterFactory"/>
<!-- <filter class="solr.EnglishPorterFilterFactory" protected="protwords.txt"/>-->
<filter class="solr.RemoveDuplicatesTokenFilterFactory"/>
</analyzer>
</fieldType>
Another issue is,it does not find strings at the end of the word. Example: I searched on “bug” and found bugs and not the word "samplebug".
It would be really helpful if you could help me on this issue..
Thanks in advance.

默认情况下，Solr 不支持左截断，例如搜索
*bug来查找samplebug。使用 solr.ReversedWildcardFilterFactory 来反转术语并以受人尊敬的方式索引热值，例如 gubelpmas 。 solr.ReversedWildcardFilterFactory
这是一个教程：http://solr.pl/en/2010/12/20/wildcard-queries-and-how-solr-handles-them/
By default Solr does not support left truncation, like searches for
*bugto findsamplebug.Use the
solr.ReversedWildcardFilterFactoryin order to reverse the term and index the therm in an revered way, likegubelpmas. solr.ReversedWildcardFilterFactoryHere is an tutorial: http://solr.pl/en/2010/12/20/wildcard-queries-and-how-solr-handles-them/
您的查询解析器似乎无法处理前导通配符搜索。
您使用什么查询解析器？
扩展 dismax 查询解析器支持使用前导通配符进行搜索。你想检查一下。
It seems your query parser is not able to handle leading wildcard searches.
What query parser are you using ?
The Extended dismax query parser supports searches with leading wildcards. you want to check for it.
