1. Use of org.compass.spring.device.hibernate.dep.SpringHibernate3GpsDevice
is now deprecated in favor of
org.compass.gps.device.hibernate.HibernateGpsDevice. This requires a
org.compass.spring.device.hibernate.SpringNativeHibernateExtractor to be
injected (see applicationContext-service.xml, below.)
2. Most users add search terms to a search in order to narrow the search.
But, by default, Compass widens the search by ORing the search terms
together. To make searches more googlesque, I have created a
CompassSearchHelper subclass (AndDefaultCompassSearchHelper) that causes
search terms to be ANDed.
First, the new AndDefaultCompassSearchHelper:
package com.firstworldtoys.util;
import org.compass.core.Compass;
import org.compass.core.CompassQuery;
import org.compass.core.CompassQueryBuilder;
import org.compass.core.CompassSession;
import org.compass.core.support.search.CompassSearchCommand;
import org.compass.core.support.search.CompassSearchHelper;
public class AndDefaultCompassSearchHelper extends CompassSearchHelper
{
public AndDefaultCompassSearchHelper(Compass compass)
{
super(compass);
}
public AndDefaultCompassSearchHelper(Compass compass, Integer pageSize)
{
super(compass, pageSize);
}
protected CompassQuery buildQuery(CompassSearchCommand searchCommand,
CompassSession session)
{
CompassQueryBuilder queryBuilder = session.queryBuilder();
return
queryBuilder.queryString(searchCommand.getQuery()).useAndDefaultOperator().toQuery();
}
}
Second, updated XML for your dispatcher-servlet.xml file:
<!-- ==== COMPASS SEARCH CONTROLLER ==== -->
<bean id="andDefaultCompassSearchHelper"
class="com.firstworldtoys.util.AndDefaultCompassSearchHelper">
<constructor-arg index="0">
<ref bean="compass"/>
</constructor-arg>
<constructor-arg index="1">
<value>10</value>
</constructor-arg>
</bean>
<bean id="searchController"
class="org.compass.spring.web.mvc.CompassSearchController">
<property name="searchHelper" ref="andDefaultCompassSearchHelper"/>
<property name="compass">
<ref bean="compass" />
</property>
<property name="searchView">
<value>searchView</value>
</property>
<property name="searchResultsView">
<value>searchResultsView</value>
</property>
<property name="pageSize">
<value>10</value>
</property>
</bean>
<!-- ==== COMPASS INDEX CONTROLLER ==== -->
<bean id="indexController"
class="org.compass.spring.web.mvc.CompassIndexController">
<property name="compassGps">
<ref bean="compassGps" />
</property>
<property name="indexView">
<value>reindexView</value>
</property>
<property name="indexResultsView">
<value>reindexResultsView</value>
</property>
</bean>
Third, updated XML for your applicationContext-service.xml file:
<!-- COMPASS START -->
<bean id="compass" class="org.compass.spring.LocalCompassBean">
<property name="classMappings">
<list>
<value>com.firstworldtoys.model.Toy</value>
</list>
</property>
<property name="compassSettings">
<props>
<prop
key="compass.engine.connection">file:///Users/gregederer/dev/fwt/compass</prop>
<prop
key="compass.transaction.factory">org.compass.spring.transaction.SpringSyncTransactionFactory</prop>
<!-- snowball analyzer provides stemming (so 'monkey' gets monkeys,
too) -->
<prop key="compass.engine.analyzer.default.type">snowball</prop>
<prop key="compass.engine.analyzer.default.name">English</prop>
</props>
</property>
<property name="transactionManager" ref="transactionManager" />
</bean>
<bean id="hibernateGpsDevice"
class="org.compass.gps.device.hibernate.HibernateGpsDevice">
<property name="name" value="hibernateDevice" />
<property name="sessionFactory" ref="sessionFactory" />
<property name="nativeExtractor">
<bean
class="org.compass.spring.device.hibernate.SpringNativeHibernateExtractor"
/>
</property>
</bean>
<bean id="compassGps" class="org.compass.gps.impl.SingleCompassGps"
init-method="start" destroy-method="stop">
<property name="compass">
<ref bean="compass" />
</property>
<property name="gpsDevices">
<list>
<bean
class="org.compass.spring.device.SpringSyncTransactionGpsDeviceWrapper">
<property name="gpsDevice" ref="hibernateGpsDevice" />
</bean>
</list>
</property>
</bean>
<!-- COMPASS END -->
Finally, here's the search JSP:
<%@ include file="/common/taglibs.jsp"%>
<html>
<head>
<title>Search</title>
</head>
<body>
Search:
<form method="GET">
<spring:bind path="command.query">
<input id="query" type="text" name="query" value="<c:out
value="${status.value}"/>" />
</spring:bind>
<p>
<input type="submit" value="Search" />
</p>
</form>
<c:if test="${! empty searchResults}">
<p>Search took <c:out value="${searchResults.searchTime}" /> ms</p>
<table border="2">
<tr>
<th>SCORE</th>
<th>TYPE</th>
<th>ID</th>
</tr>
<c:forEach var="hit" items="${searchResults.hits}">
<tr>
<td><fmt:formatNumber type="percent" value="${hit.score}"
/></td>
<td><c:out value="${hit.alias}" /></td>
<td><c:out value="${hit.data.id}" /></td>
</tr>
</c:forEach>
</table>
</c:if>
</body>
</html>
