Words within long string not searchable in Confluence

Steps to replicate

1. Create a page and insert the following log extract

   2016-02-16 23:37:05,328 WARN [http-nio-8090-exec-7] [atlassian.config.xml.AbstractDom4jXmlConfigurationPersister]
   

2. Search for the string "AbstractDom" and notice that it cannot be found.
3. Search for the page title or the entire string "atlassian.config.xml.AbstractDom4jXmlConfigurationPersister" and it's searchable.

Thing(s) to note

• Reindex doesn't help.
• Inserting wild cards also doesn't help. Example

  *AbstractDom*
