Question

I am working on rails application and which is based on Apache Solr search engine and we are using Sunspot gem. But I am facing one problem, If I search query house rent then its giving me thousands of results by using and query . But the results what I am getting are not relevant.

I am expecting the documents which contains the house and rent words near to each other, those documents should come on top. But for now the documents which contains more number of house and rent documents are coming on top. But there is no any word proximity.

My schema.xml contains following definition:

<fieldType name="text" class="solr.TextField" omitNorms="false">
  <analyzer>
    <tokenizer class="solr.PatternTokenizerFactory" pattern="[\s,\.;\(\)]+"/>
    <filter class="solr.StandardFilterFactory"/>
    <filter class="solr.LowerCaseFilterFactory"/>
    <filter class="solr.StopFilterFactory" words="stopwords.txt" ignoreCase="true"/>
    <charFilter class="solr.HTMLStripCharFilterFactory"/>
    <filter class="solr.PorterStemFilterFactory"/>
  </analyzer>
</fieldType>

To achieve this what changes are need to do? or any filter are necessary to add for this?

Answer 1

You can try this

<fieldType name="shingleString" class="solr.TextField" positionIncrementGap="100" omitNorms="true">
      <analyzer type="index">
        <tokenizer class="solr.KeywordTokenizerFactory"/>
      </analyzer>
      <analyzer type="query">
        <tokenizer class="solr.WhitespaceTokenizerFactory"/>
        <filter class="solr.ShingleFilterFactory" outputUnigrams="true" outputUnigramIfNoNgram="true" maxShingleSize="99"/>
        <filter class="solr.PositionFilterFactory" />
      </analyzer>
    </fieldType>

使用词组字段来增强它们，或者您可以尝试增强术语如"house rent"~5
