Как сделать поиск нескольких слов в SOLRJQuery

Question

В настоящее время я работаю с SolrJ API для нашего веб-приложения. Нам нужно иметь несколько слов в приложении. Но я не знаю, как это сделать.

Вот код, который мы разработали до сих пор, ища в Интернете.

HttpSolrClient solr = new HttpSolrClient("http://localhost:8983/solr/Test"); 
SolrQuery query = new SolrQuery();   
query.setQuery("product_name:Dell laptop*"); 
query.setFields("product_name"); 
query.setStart(0); 
query.setRows(1000); 

QueryResponse response = solr.query(query); 
SolrDocumentList results = response.getResults(); 
for (int i = 0; i < results.size(); ++i) { 
    System.out.println(results.get(i)); 
} 

Но я не получаю никакого результата. У нашего Solr есть слияние mongo DB с помощью админ-консоли apache Solr, работающей на порту 8983.

Пожалуйста, помогите. Я новичок в apache SOLR.

Update: Вот schema.xml мы создали

Мы создали новый schema.xml, удаляя ненужные ссылки здесь схемы мы использовали.

<schema name="example" version="1.5"> 

<field name="_version_" type="long" indexed="true" stored="true"/> 
<field name="_root_" type="string" indexed="true" stored="false"/> 

     <fields>  
     <field name="id" type="long" indexed="true" stored="true" required="true" multiValued="false" /> 
     <field name="product_name" type="string" indexed="true" stored="true" required="true" /> 
     <field name="product_price" type="" indexed="true" stored="true" required="true" /> 

    </fields> 
    <uniqueKey>id</uniqueKey> 
    <types> 
       <fieldType name="string" class="solr.StrField" sortMissingLast="true" omitNorms="true"/> 
       <fieldType name="long" class="solr.TrieLongField" precisionStep="0" omitNorms="true" positionIncrementGap="0" /> 
       <fieldType name="text_wslc" class="solr.TextField" positionIncrementGap="100"> 
         <analyzer type="index"> 
           <tokenizer class="solr.WhitespaceTokenizerFactory"/> 
           <filter class="solr.LowerCaseFilterFactory"/> 
         </analyzer> 
         <analyzer type="query"> 
           <tokenizer class="solr.WhitespaceTokenizerFactory"/> 
           <filter class="solr.LowerCaseFilterFactory"/> 
         </analyzer> 
       </fieldType> 
       <fieldType name="tdouble" class="solr.TrieDoubleField" precisionStep="8" positionIncrementGap="0"/> 
       <fieldType name="location" class="solr.LatLonType" subFieldSuffix="_coordinate"/> 
       <fieldType name="tdate" class="solr.TrieDateField" omitNorms="true" precisionStep="6" positionIncrementGap="0"/> 
     <fieldType name="double" class="solr.TrieDoubleField" precisionStep="0" positionIncrementGap="0"/> 
    </types> 

     <defaultSearchField>product_name</defaultSearchField> 

     <!-- we don't want too many results in this usecase --> 
     <solrQueryParser defaultOperator="AND"/> 

      </schema> 

Answer 2

То, что вы работаете в упомянута в JavaDoc Lucene. Почему Луцен? Синтаксис запроса Solr - это надмножество Lucene. As mentioned there

Примечание: Поле действует только на срок, что он непосредственно предшествует, так что название запроса

: Сделайте это прямо

Останется только найти «Do» в поле заголовка. Он найдет «это» и «право» в поле по умолчанию (в этом случае текстовое поле).

В вашем случае только Dell направлена ​​на поле корпуса PRODUCT_NAME, остальное направляется в поле поиска по умолчанию, определенных в конфигурации.

Что вы хотите использовать, чтобы обойти это, называется Field Grouping. Поэтому вы должны окружить слова, которые должны идти в одном поле с круглыми скобками, как этот

SolrQuery query = new SolrQuery();   
query.setQuery("product_name:(Dell laptop*)"); // surround the words with (...) 
query.setFields("product_name"); 
query.setStart(0); 
query.setRows(1000);
