Question

Solr, how can I get the original term first than the original version?

I am trying to get the exact key result first from the Solr 5.0.0 result.

For example,

Meditation bowls
Goddess Bowles
Heavenly bowls
Bowling green
33 bowls Tibetan chants
Rebirth of a dusty bowl
Bowl of stars

If I search for a word bowl

, the expected results are:

Rebirth of a dusty bowl
Bowl of stars
Meditation bowls
Goddess Bowles
Heavenly bowls
Bowling green
33 bowls Tibetan chants

The exact word containing the results shoud comes first. My schematic is shown below:

 <fieldType name="text_wslc" class="solr.TextField" positionIncrementGap="100">
   <analyzer type="index">
     <tokenizer class="solr.WhitespaceTokenizerFactory"/>
     <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" ignoreCase="true" expand="true"/>
     <filter class="solr.WordDelimiterFilterFactory"
                             generateWordParts="1"
                             generateNumberParts="1"
                             catenateWords="1"
                             catenateNumbers="1"
                             catenateAll="1"
                             preserveOriginal="1"
                             />
     <filter class="solr.LowerCaseFilterFactory"/>
     <filter class="solr.KeywordRepeatFilterFactory"/>
     <filter class="solr.PorterStemFilterFactory"/>
     <filter class="solr.KStemFilterFactory"/>
     <filter class="solr.RemoveDuplicatesTokenFilterFactory"/>
   </analyzer>
   <analyzer type="query">
     <tokenizer class="solr.WhitespaceTokenizerFactory"/>
     <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" ignoreCase="true" expand="true"/>
     <filter class="solr.WordDelimiterFilterFactory"
                             generateWordParts="1"
                             generateNumberParts="1"
                             catenateWords="1"
                             catenateNumbers="1"
                             catenateAll="1"
                             preserveOriginal="1"
                             />
     <filter class="solr.LowerCaseFilterFactory"/>
     <filter class="solr.KeywordRepeatFilterFactory"/>
     <filter class="solr.PorterStemFilterFactory"/>
     <filter class="solr.KStemFilterFactory"/>
     <filter class="solr.RemoveDuplicatesTokenFilterFactory"/>
   </analyzer>
 </fieldType>

I've seen usage KeywordRepeatFilterFactory

give the exact consistent and then the version. But that doesn't work for me.

You can add another field to schema.xml . This one will contain a copy of the original field:

<field name="title" type="text_wslc" indexed="true" stored="true"/>
<field name="titleExact" type="text_wslcExact" indexed="true" stored="true"/>
<copyField source="title" dest="titleExact"/>

Where text_wslcExact

something like this:

<fieldType name="textExact" class="solr.TextField" positionIncrementGap="100" >
  <analyzer type="index">
    <tokenizer class="solr.WhitespaceTokenizerFactory"/>
    <filter class="solr.LimitTokenCountFilterFactory" maxTokenCount="20"/>
    <filter class="solr.LowerCaseFilterFactory"/>
  </analyzer>
  <analyzer type="query">
    <tokenizer class="solr.WhitespaceTokenizerFactory"/>
    <filter class="solr.LimitTokenCountFilterFactory" maxTokenCount="20"/>
    <filter class="solr.LowerCaseFilterFactory"/>
  </analyzer>

The next thing to do is add (and enlarge) this new field to your query. So, in your solrconfig.xml file , try something like this:

<str name="qf">title titleExact^10</str>
<str name="pf">title^10 titleExact^100</str>

Here is my source where you can get all the explanations.
