Hi Kaji, many thanks for your suggestion.
Sorry for delay in my feedback.
I've tried to set hl.usePhraseHighlighter=true, but it still not working.
Here my setup:
<highlighting>
<!-- Configure the standard fragmenter -->
<!-- This could most likely be commented out in the "default" case -->
<fragmenter name="gap" class="org.apache.solr.highlight.GapFragmenter">
<lst name="defaults">
<int name="hl.fragsize">100</int>
<bool name="hl.usePhraseHighlighter">true</bool>
<bool name="hl.highlightMultiTerm">true</bool>
</lst>
</fragmenter>
<!-- A regular-expression-based fragmenter (f.i., for sentence
extraction) -->
<fragmenter name="regex"
class="org.apache.solr.highlight.RegexFragmenter" default="true">
<lst name="defaults">
<!-- slightly smaller fragsizes work better because of slop -->
<int name="hl.fragsize">100</int>
<!-- allow 50% slop on fragment sizes -->
<float name="hl.regex.slop">0.5</float>
<!-- a basic sentence pattern -->
<str name="hl.regex.pattern">[-\w ,/\n\"']{20,200}</str>
<bool name="hl.usePhraseHighlighter">true</bool>
<bool name="hl.highlightMultiTerm">true</bool>
</lst>
</fragmenter>
<!-- Configure the standard formatter -->
<formatter name="html" class="org.apache.solr.highlight.HtmlFormatter">
<lst name="highlighting">
<bool name="hl.usePhraseHighlighter">true</bool>
<bool name="hl.highlightMultiTerm">true</bool>
<str name="hl.simple.pre"><![CDATA[<strong>]]></str>
<str name="hl.simple.post"><![CDATA[</strong>]]></str>
</lst>
</formatter>
</highlighting>
Any help from other user is really appreciated.
