具有数字

Question

我目前正在使用apache solr，我为搜索文本字段实现了自动完成功能。它适用于字母，但我现在遇到的问题是数字。尽管我的索引中有数字，但数字不会自动完成。有谁知道这种问题？

继承我的schema.xml：

    <fieldType name="suggest_de" class="solr.TextField" positionIncrementGap="100">
                <analyzer type="index">
                    <tokenizer class="solr.KeywordTokenizerFactory" />
                    <filter class="solr.LowerCaseFilterFactory" />
                    <filter class="solr.WordDelimiterFilterFactory"
                            splitOnCaseChange="0" splitOnNumerics="0"
                            generateWordParts="1" generateNumberParts="0" catenateWords="0"
                            catenateNumbers="1" catenateAll="0" preserveOriginal="1"/>
                    <filter class="de.hybris.platform.solrfacetsearch.ysolr.synonyms.HybrisSynonymFilterFactory" ignoreCase="true" synonyms="de" coreName="${solr.core.name}"/>
                    <filter class="de.hybris.platform.solrfacetsearch.ysolr.stopwords.HybrisStopWordsFilterFactory" ignoreCase="true" lang="de" coreName="${solr.core.name}"/>
                    <filter class="solr.StopFilterFactory" words="solr/embedded/conf/stopwords_de.txt" ignoreCase="true" />
                    <filter class="solr.TrimFilterFactory" />
                    <filter class="solr.RemoveDuplicatesTokenFilterFactory" />
                </analyzer>
                <analyzer type="query">
                    <tokenizer class="solr.KeywordTokenizerFactory" />
                    <filter class="solr.LowerCaseFilterFactory" />
                </analyzer>
            </fieldType>

<field name="autosuggest" type="string" indexed="true" stored="true" multiValued="true" />
        <field name="autosuggest_de" type="suggest_de" indexed="true" stored="true" multiValued="true" />

        <copyField source="autosuggest" dest="autosuggest_de" />

和我的solrconfig.xml：

<requestHandler name="/suggest" class="solr.SearchHandler">
        <lst name="defaults">
            <str name="spellcheck">true</str>
            <str name="spellcheck.dictionary">default</str>
            <str name="spellcheck.onlyMorePopular">true</str>
            <str name="spellcheck.count">10</str>
            <str name="spellcheck.collate">true</str>
            <str name="mm">100%</str>
        </lst>
        <arr name="components">
            <str>suggest</str>
        </arr>
    </requestHandler>

<searchComponent name="suggest" class="solr.SpellCheckComponent">
        <str name="queryAnalyzerFieldType">autosuggest</str>
        <lst name="spellchecker">
            <str name="name">default</str>
            <str name="classname">org.apache.solr.spelling.suggest.Suggester</str>
            <str name="lookupImpl">org.apache.solr.spelling.suggest.tst.TSTLookup</str>
            <str name="field">autosuggest_de</str>
            <str name="buildOnOptimize">true</str>
            <str name="accuracy">0.35</str>
            <str name="characterEncoding">UTF-8</str>
        </lst>
        <lst name="spellchecker">
            <str name="name">de</str>
            <str name="classname">org.apache.solr.spelling.suggest.Suggester</str>
            <str name="lookupImpl">org.apache.solr.spelling.suggest.tst.TSTLookup</str>
            <str name="field">autosuggest_de</str>
            <str name="buildOnOptimize">true</str>
            <str name="accuracy">0.35</str>
            <str name="characterEncoding">UTF-8</str>
        </lst>
    </searchComponent>

正如我所说，字母没有问题，但是在查询中不会返回以数字开头的所有内容。
