Hi Shyam,
>From the mail thread:

Thanks for the response when I use hl.bs.chars=".!?" and hl.bs.maxScan=200 I
see improvements, below is the highlighted value
"The synthesis tool only supports the resolution functions for
<em>std_logic</em> and std_logic_vector."
But in other cases I also see that some of the words break in between as shown
below
Original text: " How Are Clock Gating Checks Inferred"
When searching for the term "clock" the highlighted text is displayed as show
below
"w Are <em>Clock</em> Gating Checks Inferred"
As you can see only w is displayed from the word How.

I couldn't reproduce your problem. I'm using trunk. I got the following snippet
that was I expected one:
{code}
<lst name="highlighting">
<lst name="2">
<arr name="includes">
<str> How Are <em>Clock</em> Gating Checks Inferred</str>
</arr>
</lst>
</lst>
{code}
My BoundaryScanner setting is:
{code}
<boundaryScanner name="default"
default="true"
class="solr.highlight.SimpleBoundaryScanner">
<lst name="defaults">
<str name="hl.bs.maxScan">100</str>
<str name="hl.bs.chars">.!?</str>
</lst>
</boundaryScanner>
{code}
My request was:
http://localhost:8983/solr/select?q=clock&hl=on&hl.fl=includes&hl.useFastVectorHighlighter=true
I'm using the following sample data that's been provided by Shyam in the mail
thread:
{code}
<add>
<doc>
<field name="id">1</field>
<field name="includes">User-defined resolution functions. The synthesis
tool only supports the</field>
<field name="includes">resolution functions for std_logic and
std_logic_vector.</field>
<field name="includes"></field>
<field name="includes">Slices with range indices that do not evaluate to
constants</field>
</doc>
<doc>
<field name="id">2</field>
<field name="includes"> How Are Clock Gating Checks Inferred</field>
</doc>
</add>
{code}
where includes field, I changed the field to multiValued in example schema.xml.
Can you verify it?
