That's not a bug with the example schema, as price is a single-
valued field. getFirstValue will work, yes, but isn't necessary
when it's single valued. If you've got multiple prices, you
probably want something like:
#foreach($price in $doc.getFieldValue('price'))$!
number.currency($price)#end
Note that in your scenario it isn't returning a string with brackets
(except to the UI) - it's truly an array within the template.
Though maybe what you want in your schema is a single valued price
field? :)
I must be missing something...
Here's what's in my schema:
<field name="price" type="float" indexed="true" stored="true"/>
Which is exactly what was in the original example schema.
I can't look at the index using the latest Luke - I'd need to rebuild
Luke with the current Lucene code, since the format is now version 10.
I tried using solr/admin/analysis, to see what a query is returning,
but I get a server error (500):

Looks like it's not happy doing analysis on a TrieFloatField.
When I do searches against the index using solr/admin, the results
only have a single value, e.g.:
<result name="response" numFound="4" start="0" maxScore="4.880418">
<doc>
<float name="score">4.880418</float>
<arr name="product_id">
<str>27126</str>
</arr>
<arr name="price">
<float>2.29</float>
</arr>
<arr name="product_name">
<str>KAS Rugs Indira Black Circles Rug</str>
</arr>
...
</doc>
</result>
Any other ideas what might be going on?
Thanks,

I noticed that my prices weren't showing up, even though I've got a
price field.
I think the issue is with this line from hit.vm:
<p><b>#field('name')</b> $!
number.currency($doc.getFieldValue('price'))</p>
The number.currency() function needs to get passed something that
looks like a number, but $doc.getFieldValue() will return "[2.96]",
because it could be a list of values.
The square brackets confuse number.currency, so you get no price.
I think this line needs to be:
<p><b>#field('name')</b> $!
number.currency($doc.getFirstValue('price'))</p>
...since getFirstValue() returns a single value without brackets.
