I'm having some trouble trying to upgrade my old hightligher
from <highlighting><fragmenter><formatter> format (1.4 version, default
config in the solr website) to the new Fast Vector highlighter.
I'm using SOLR 3.3.0 with <luceneMatchVersion>LUCENE_33</luceneMatchVersion>
in <config>
In my solrconfig.xml i added these lines
in the default request handler:
<bool name="hl.useFastVectorHighlighter">true</bool>
<bool name="hl.usePhraseHighlighter">true</bool>
<bool name="hl.highlightMultiTerm">true</bool>
<str name="hl.fragmentsBuilder">colored</str>
and
<fragmentsBuilder name="colored"
class="org.apache.solr.highlight.ScoreOrderFragmentsBuilder">
<lst name="defaults">
<str name="hl.tag.pre"><![CDATA[
<b style="background:yellow">,<b style="background:lawgreen">,
<b style="background:aquamarine">,<b style="background:magenta">,
<b style="background:palegreen">,<b style="background:coral">,
<b style="background:wheat">,<b style="background:khaki">,
<b style="background:lime">,<b
style="background:deepskyblue">]]></str>
<str name="hl.tag.post"><![CDATA[</b>]]></str>
</lst>
</fragmentsBuilder>
All I get is: ('grave' means severe)

Docs in http://wiki.apache.org/solr/HighlightingParameters say:
hl.fragmentsBuilder
Specify the name of
SolrFragmentsBuilder<http://wiki.apache.org/solr/SolrFragmentsBuilder>
. [image: <!>] Solr3.1 <http://wiki.apache.org/solr/Solr3.1> This parameter
makes sense for
FastVectorHighlighter<http://wiki.apache.org/solr/FastVectorHighlighter>
only.
SolrFragmentsBuilder
<http://wiki.apache.org/solr/SolrFragmentsBuilder> respects
hl.tag.pre/post parameters:
<!-- multi-colored tag FragmentsBuilder -->
<fragmentsBuilder name="colored"
class="org.apache.solr.highlight.ScoreOrderFragmentsBuilder">
<lst name="defaults">
<str name="hl.tag.pre"><![CDATA[
<b style="background:yellow">,<b style="background:lawgreen">,
<b style="background:aquamarine">,<b style="background:magenta">,
