Searching for the following string in the Topic XML field: </hibernate-configuration>]]> ends up blanking out the Topic XML search field and giving you every topic in the DB as a result.
Fixed in 20111006-0733 Topic.getFieldValue() incorrectly referenced the TOPIC_XML_FILTER_VAR_DESC constant, instead of the TOPIC_XML_FILTER_VAR constant.
It seems to work but it doesn't find any results. I searched for <bridgehead> and <variablelist>, and both came up with empty results.
http://jboss-eap.bne.redhat.com:8080/TopicIndex/CustomSearchTopicList.seam?topicXml=%3Cvariablelist%3E brings up 36 topics. A SQL query of <bridgehead> returns no records, so this is also correct.
Odd, you are right. I don't know why my query for <variablelist> didn't work. However, when you click "Back to Search" your previous search term is moved from Topic XML to Topic Description, now.
