将文档 ID 写入索引的异常；可能的分析错误 [英] Exception writing document id to the index; possible analysis error

问题描述

我在索引文档时遇到上述错误.

I am getting the above error while indexing the documents.

<field name="a_suggest" type="my_suggest_field" indexed="true" stored="false"/>
<field name="b_suggest" type="my_suggest_field" indexed="true" stored="false" />
<field name="c_suggest" type="my_suggest_field" indexed="true" stored="false"/>

  <fieldType name="my_suggest_field" class="solr.TextField" positionIncrementGap="100">
    <analyzer type="index">
        <tokenizer class="solr.WhitespaceTokenizerFactory"/>
        <filter class="solr.LowerCaseFilterFactory" />
        <filter class="solr.EdgeNGramFilterFactory" maxGramSize="10" minGramSize="2"/>
    </analyzer>
    <analyzer type="query">
        <tokenizer class="solr.StandardTokenizerFactory" />
        <filter class="solr.LowerCaseFilterFactory" />
    </analyzer>
  </fieldType>

我在调用时出错..

server.add(documents);

首先，可能的分析错误是什么意思?是否与 my_suggest_field 索引分析器有关.是不是因为索引分析器中的标记、过滤器的顺序?

First of all, what is the meaning of Possible analysis error? Is it related to my_suggest_field index analyzer. Is it due to the order of the tokens, filters in the index analyzer?

谢谢.

推荐答案

我需要为 EdgeNGramFilterFactory 和正常建议创建一个单独的字段类型.

I need to create a separate field types for EdgeNGramFilterFactory and normal suggest.

  <field name="my_suggest" type="my_suggest_field" indexed="true" stored="false"/>
  <field name="my_suggest_ngram" type="my_suggest_ngram_field" indexed="true" stored="false"/>

  <fieldType name="my_suggest_field" class="solr.TextField" positionIncrementGap="100">
    <analyzer type="index">
        <filter class="solr.LowerCaseFilterFactory" />
        <tokenizer class="solr.WhitespaceTokenizerFactory"/>
    </analyzer>
    <analyzer type="query">
        <tokenizer class="solr.StandardTokenizerFactory" />
        <filter class="solr.LowerCaseFilterFactory" />
    </analyzer>
  </fieldType>

  <fieldType name="my_suggest_ngram_field" class="solr.TextField" positionIncrementGap="100">
        <analyzer type="index">
            <filter class="solr.LowerCaseFilterFactory" />
            <tokenizer class="solr.WhitespaceTokenizerFactory"/>
            <filter class="solr.EdgeNGramFilterFactory" minGramSize="2" maxGramSize="10"/>
        </analyzer>
        <analyzer type="query">
            <tokenizer class="solr.StandardTokenizerFactory" />
            <filter class="solr.LowerCaseFilterFactory" />
        </analyzer>
  </fieldType>
