In my Solr (3.3) configuration I specified these two params:
<str name="hl.simple.pre"><![CDATA[<b>]]></str>
<str name="hl.simple.post"><![CDATA[</b>]]></str>
when I do a simple search I obtain correctly highlighted results where
matches areenclosed with correct tag.
If I do the same request with hl.useFastVectorHighlighter=true in the
http query string (or specifying the same parameter in the config file)
the metches are enclosed with <em> tag (the default value).
Anyone has encountered the same issue?
