Hi group,
I'm trying to highlight my complete(!) XML document, which is indexed for that
purpose in a special field called "wkxmlsource". I configured the "wkxmlsource"
field like
<field indexed="true" multiValued="false" name="wkxmlsource" omitNorms="true"
stored="true" termPositions="true" termOffsets="true" termVectors="true"
type="text_xml"/>
And the text_xml fieldtype is almost equal to the text_en field, but with the
<charFilter class="solr.HTMLStripCharFilterFactory" /> as the first class in
the index analyzer. That prevents highlighting inside XML tags.
First I tried the simple highlighter and that almost worked: I get my document
back with my search terms and phrases highlighted, each individual term gets it
own highlight tags. But the problem is that not the complete value of field
"wkxmlsource" is returned; it cuts off the bottom part, no matter how big I set
the hl.fragsize.
So my next try was to use the FVH (hl.useFastVectorHighlighter=true) instead.
That helped: it returns now the complete value of "wkxmlsource" with all my
search terms/phrases highlighted. But...in case of a phrase search, it doesn't
highlight each individual term anymore, but it only puts highlight tags around
the complete phrase. That could possible lead to malformed XML. An example:
Search for phrase: "across the country Santa Fe" it highlights like this in the
document:
<para align="left">...spread <em>across the country.</para><para
align="left">Santa Fe</em> Pacific... </para>
How can I let the FVH highlight individual terms instead of the complete
phrase? Ideally I like to have something like:
<para align="left">...spread <em>across</em> <em>the</em>
<em>country</em>.</para><para align="left"><em>Santa</em> <em>Fe</em>
Pacific... </para>
which is still valid XML.
My boundaryscanner is configured like:
<boundaryScanner
name="breakIterator" class="solr.highlight.BreakIteratorBoundaryScanner">
<lst
name="defaults">
<str name="hl.bs.type">WORD</str>
<str name="hl.bs.language">en</str>
<str name="hl.bs.country">US</str>
</lst>
</boundaryScanner>
Thanks, Tom
