Novactive eZ Solr Search Extra Bundle

Exact matches boosting

To allow boosting content where the search is exactly matched (accent, case, ...) you need to add the following settings to your solr schema.xml

Add a new fieldtyp "rawtext", copy of the "text" fieldtype and remove the filter with are supposed to modify the text :

  • LowerCaseFilterFactory
  • FrenchLightStemFilterFactory
  • ASCIIFoldingFilterFactory
  • ...

Example for the french language

<!-- French -->
<fieldType name="text" class="solr.TextField" positionIncrementGap="100">
<analyzer>
    <tokenizer class="solr.StandardTokenizerFactory"/>
    <filter class="solr.LowerCaseFilterFactory"/>
    <!-- removes l', etc -->
    <filter class="solr.ElisionFilterFactory" ignoreCase="true" articles="contractions_fr.txt"/>
    <filter class="solr.WordDelimiterFilterFactory"
            generateWordParts="1"
            generateNumberParts="1"
            catenateWords="0"
            catenateNumbers="0"
            catenateAll="0"
            preserveOriginal="1"
    />
    <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords_fr.txt" format="snowball" />
    <filter class="solr.FrenchLightStemFilterFactory"/>
    <!-- less aggressive: <filter class="solr.FrenchMinimalStemFilterFactory"/> -->
    <!-- more aggressive: <filter class="solr.SnowballPorterFilterFactory" language="French"/> -->
</analyzer>
</fieldType>

<fieldType name="rawtext" class="solr.TextField" positionIncrementGap="100">
<analyzer>
    <tokenizer class="solr.StandardTokenizerFactory"/>
    <!-- removes l', etc -->
    <filter class="solr.ElisionFilterFactory" ignoreCase="true" articles="contractions_fr.txt"/>
    <filter class="solr.WordDelimiterFilterFactory"
            generateWordParts="1"
            generateNumberParts="1"
            catenateWords="0"
            catenateNumbers="0"
            catenateAll="0"
            preserveOriginal="1"
    />
    <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords_fr.txt" format="snowball" />
</analyzer>
</fieldType>

And lastly, add the following dynamic and copy field declaration :

<dynamicField name="*_t_raw" type="rawtext" indexed="true" stored="true" multiValued="true" omitNorms="false"/>
<copyField source="*_t" dest="*_t_raw"/>
