I just upgraded to trunk to try to fix an issue I was having with the highlighter described in JIRA 1826, but it appears that this issue still exists on trunk. I'm running the following query
subject:ztest* subject is a text field (not multivalued) and the return in highlighting is <em>ZTest</em>For<em>ZTestForJamie</em> the actual stored value is "ZTestForJamie". Is anyone else experiencing this?
