Class TaxonomyRankQueryFilter

java.lang.Object
  com.raritantechnologies.searchApp.QueryProcessorFilter
      com.raritantechnologies.verity.parametric.queryFilters.TaxonomyRankQueryFilter

All Implemented Interfaces:

IQueryProcessor

public class TaxonomyRankQueryFilter

extends QueryProcessorFilter

Supports ranking of documents within a Parametric Index Taxonomy node. Coordinates with XML result record in which a taxonomy node ID has been indexed as a zone with a rank

    <TaxID_[Taxonomy_ID]>0.85</TaxID_[Taxonomy_ID]>

 

Takes a query input. If the "taxonomy name" parameter is in the input, indicating that a user has selected this taxonomy node, the filter creates a cooked VQL query that it adds to the inputParameter map. To create the query, the filter first looks up the taxonomy node id given the name of the taxonomy and its value in the input parameter map from a taxonomy ID lookup source. It then constructs a cooked query for a range of scores. This "maps" the taxonomy score to a Verity relevance score.

Note that we are working with XML zones here so we cannot do much Math!

Set searchType to search all (not search within).

XML Configuration Template:

 <SourceType name="rankedTaxonomyNodes"
           type="QueryProcessorFilterSource"
           sourceFactoryClass = "com.raritantechnologies.searchApp.QueryProcessorFilterFactory"
           filterClass  = "com.raritantechnologies.verity.parametric.queryFilters.TaxonomyRankQueryFilter"
           inputSource  = "Parametric Filter Source"
           queryParam="query"
           taxIDPrefix="TaxID_" >

  <TaxonomyFields>
   <Field name="the tax field name" rootPath="its root path value" />
   <Field name="another taxonomy field" rootPath="its root path value" />
  </TaxonomyFields>

  <ScoreMap>
     <Score value="1*" relevance="1.0" />
     <Score value="9*" relevance="0.9" />
     <Score value="8*" relevance="0.8" />
     <Score value="7*" relevance="0.7" />
     <Score value="6*" relevance="0.6" />
  </ScoreMap>

  <TaxonomyIDLookup name="search sourceName" taxNameField="input field ID for full taxonomy path"
                                                outputField="output field with Taxonomy ID" />
  
 </SourceType>
 

Sample VQL:

   <or>( ( [0.8]( ( (8*) <in> TaxID_255 ))), ( [0.7]( ( (7*) <in> TaxID_255))))
