使用solr.WordBreakSolrSpellChecker建议破碎的单词

Question

我索引了电子电子商务产品目录。

这是我收藏的典型文件：

"docs": [
      {
        "prezzo_vendita_d": 39.9,
        "codice_produttore_s": "DK00150020",
        "codice_s": "5.BAT.27407",
        "descrizione": "BATTERIA GO PRO HERO ",
        "barcode_interno_s": "185323000958",
        "categoria": "Batterie",
        "prezzo_acquisto_d": 16.12,
        "marchio": "GO PRO",
        "data_aggiornamento_dt": "2012-06-21T00:00:00Z",
        "id": "27407",
        "_version_": 1491274123542790100
      },
  {
    "codice_produttore_s": "DK0052043",
    "codice_s": "05.SP.42760",
    "id": "42760",
    "marchio": "SP GADGETS",
    "barcode_interno_s": "4028017520430",
    "prezzo_acquisto_d": 34.4,
    "data_aggiornamento_dt": "2014-11-04T00:00:00Z",
    "descrizione": "SP POS CASE GOPRO OLIVE LARGE",
    "prezzo_vendita_d": 59.95,
    "_version_": 1491274406746390500
  }
...]

我希望我的拼写检查器能够建议＆＃34;去亲＆＃34;用户搜索＆＃34; gopro＆＃34; （没有空格）。

我也希望用户搜索＆＃34; go pro＆＃34;找到＆＃34; gopro＆＃34;产品也是。

这里有一点我的配置：

schema.xml中

<field name="marchio" type="string" indexed="true" stored="true"/>
        <field name="categoria" type="string" indexed="true" stored="true"/>
        <field name="fornitore" type="string" indexed="true" stored="true"/>
        <field name="descrizione" type="string" indexed="true" stored="true"/>

        <field name="catch_all_original" type="text_general" indexed="true" stored="false" multiValued="true" />
        <field name="catch_all" type="text_it" indexed="true" stored="false" multiValued="true" />

<copyField source="marchio" dest="catch_all" />
    <copyField source="categoria" dest="catch_all" />
    <copyField source="descrizione" dest="catch_all" />
    <copyField source="fornitore" dest="catch_all" />

    <copyField source="marchio" dest="catch_all_original" />
    <copyField source="categoria" dest="catch_all_original" />
    <copyField source="descrizione" dest="catch_all_original" />
    <copyField source="fornitore" dest="catch_all_original" />
...

        <fieldType name="text_it" class="solr.TextField" positionIncrementGap="100">
            <analyzer type="index">
                <tokenizer class="solr.WhitespaceTokenizerFactory"/>
                <filter class="solr.WordDelimiterFilterFactory" generateWordParts="1" generateNumberParts="1" catenateWords="1" catenateNumbers="1" catenateAll="0" splitOnCaseChange="1" preserveOriginal="1" />

                <filter class="solr.ElisionFilterFactory" ignoreCase="true" articles="lang/contractions_it.txt"/>

                <filter class="solr.StopFilterFactory" ignoreCase="true" words="lang/stopwords_it.txt" format="snowball" />
                <filter class="solr.ItalianLightStemFilterFactory"/>
            </analyzer>
            <analyzer type="query">
                <tokenizer class="solr.WhitespaceTokenizerFactory"/>
                <filter class="solr.WordDelimiterFilterFactory" generateWordParts="1" generateNumberParts="1" catenateWords="1" catenateNumbers="1" catenateAll="0" splitOnCaseChange="1" preserveOriginal="1" />

                <filter class="solr.ElisionFilterFactory" ignoreCase="true" articles="lang/contractions_it.txt"/>
                <filter class="solr.LowerCaseFilterFactory"/>
                <filter class="solr.ASCIIFoldingFilterFactory"/>
                <filter class="solr.StopFilterFactory" ignoreCase="true" words="lang/stopwords_it.txt" format="snowball" />

                <filter class="solr.ItalianLightStemFilterFactory"/>
                <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" ignoreCase="true" expand="true"/>
            </analyzer>
        </fieldType>

的solr-config.xml中

拼写检查器是正确的解决方案，还是其他的情况，例如＆＃34;更像是＆＃34;功能？

谢谢
