switching on hl.requireFieldMatch reducing highlighted fields returned

[Robert Brown <ro...@intelcompute.com>]

I have a query which is highlighting 3 snippets in 1 field, and 1 
snippet in another field.

By enabling hl.requireFieldMatch, only the latter highlighted field is 
returned.

from this...

<lst name="highlighting">
<lst name="348231">
<arr name="content_stemmed">
<str>
plc Whetstone Temporary [hl-on]Sales[hl-off] Assistant Customer 
service Cashier work 08
</str>
<str>
and customer queries. 07 / 99 – 2003 Debenhams Central London 
[hl-on]Sales[hl-off] Adviser Customer
</str>
<str>

merchandising; Dealing

jewellery, e.g. setting stones

</arr>
<arr name="skills_stemmed">
<str>
[hl-on]product[hl-off] knowledge [hl-on]sales[hl-off] experience
</str>
</arr>
</lst>
</lst>


to this...

<lst name="highlighting">
<lst name="348231">
<arr name="skills_stemmed">
<str>product knowledge [hl-on]sales[hl-off] experience</str>
</arr>
</lst>
</lst>


I'm doing this so the word "product" and it's variants are NOT 
highlighted - they match against a different field.
