Regex search not working, not supported?

[aeisenberg]

I am doing a search for this cl*ss. I would expect that this would match a cl, then any number of chars and then ss. The results do not reflect this. I can't quite interpret why some matches are returned. For example, in this file:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.1.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd">

    <context:annotation-config />
    <context:spring-configured/>

    <bean id="transactionManager" class="org.springframework.transaction.jta.JtaTransactionManager">
        <property name="transactionManager">
            <bean id="jotm" class="org.springframework.data.neo4j.transaction.JotmFactoryBean"/>
        </property>
    </bean>

    <bean class="org.neo4j.test.ImpermanentGraphDatabase" destroy-method="shutdown">
        <constructor-arg>
            <map>
               <entry key="tx_manager_impl" value="spring-jta"/>
            </map>
        </constructor-arg>
    </bean>

    <tx:annotation-driven mode="aspectj" transaction-manager="transactionManager"/>
</beans

There are matches on lines 6, 7, 8, and 13. But clicking on any of these matches only takes me to the first line of the file.
