Demo Configuration

Demo Configuration
Prev	Chapter 4. Sensei Demo	Next

The configuration for the demo application can be found at: https://github.com/javasoze/sensei/tree/master/conf, which contains the following files:

sensei.properties: main configuration file, describes the overall configuration of the system (we will dig into that in detail later)
schema.xml: this describes the data model and the faceting behavior of the application
custom-facets.xml: Spring file for adding custom facets, while Sensei comes with a set of facet types out of the box, this allows user-defined facets to be plugged into the application
plugins.xml: any other plug-ins, e.g. Analyzer, Similarity, and Interpreter.

Data Model

The data model is described in schema.xml:

 <table uid="id" delete-field="" skip-field="">
   <column name="color" type="string" />
   <column name="category" type="string" />
   <column name="city" type="string" />
   <column name="makemodel" type="string" />
   <column name="year" type="int" />
   <column name="price" type="float" />
   <column name="mileage" type="int" />
   <column name="tags" type="string" multi="true" delimiter=","/>
   <column name="contents" type="text" index="ANALYZED" store="NO" termvector="NO" />  
 </table>
 
 <facets>
   <facet name="color" type="simple" depends=""/>
   <facet name="category" type="simple" />
   <facet name="city" type="path">
     <params>
       <param name="separator" value="/" />
     </params>
   </facet>
   <facet name="makemodel" type="path" />
   <facet name="year" type="range">
     <params>
       <param name="range" value="1993-1994" />
       <param name="range" value="1995-1996" />
       <param name="range" value="1997-1998" />
       <param name="range" value="1999-2000" />
       <param name="range" value="2001-2002" />
     </params>
   </facet>
   <facet name="mileage" type="range">
     <params>
       <param name="range" value="*-12500" />
       <param name="range" value="12501-15000" />
       <param name="range" value="15001-17500" />
       <param name="range" value="17501-*" />
     </params>
   </facet>
   <facet name="price" type="range">
        <params>
          <param name="range" value="*,6700" />
          <param name="range" value="6800,9900" />
          <param name="range" value="10000,13100" />
          <param name="range" value="13200,17300" />
          <param name="range" value="17400,*" />
       </params>
   </facet>
   <facet name="tags" type="multi" />
 </facets>

This corresponds to the following data table:

	color	category	city	makemodel	year	price	mileage	tags	contents
meta/structured	yes	yes	yes	yes	yes	yes	yes	yes	no
type	string	string	string	string	int	float	int	string	text
facet	simple	simple	path	path	range	range	range	multi	N/A
