Re: White space in facet values
you should try fq=Product:Electric Guitar How do I handle facet values that contain whitespace? Say I have a field Product that I want to facet on. A value for Product could be Electric Guitar.

RE: White space in facet values
The phrase solution works as does escaping the space with a backslash: fq=Product:Electric\ Guitar ... actually a lot of characters need to be escaped like this (amperstands and parenthesis come to mind)... I assume you already have this indexed as string, not text...

One way to avoid escaping is to use the raw or term query parsers:
fq={!raw f=Product}Electric Guitar
In 4.0-dev, use {!term} since that will work with field types that
need to transform the external representation into the internal one
(like numeric fields need to do).

Re: White space in facet values
Another technique, which works great for facet fq's and avoids the need
to worry about escaping, is using the field query parser instead:
fq={!field f=Product}Electric Guitar
Using the field query parser avoids the need for ANY escaping of your
value at all, which is convenient in the facetting case -- you still
need to URI-escape (ampersands for instance), but you shouldn't need to
escape any Solr special characters like parens or double quotes or
anything else, if you've made your string suitable for including in a
URI. With the field query parser, a lot less to worry about.

Re: White space in facet values
Huh, does !term in 4.0 mean the same thing as !field in 1.4? What you
describe as !term in 4.0 dev is what I understand as !field in 1.4 doing.

There is a subtle distinction between {!field}, {!raw}, and {!term} which
i attempted to explain on slides 26 and 43 in this presentation...
http://people.apache.org/~hossman/apachecon2010/facets/
(you can use the HTML controls or print preview to view the notes i had
when giving it)
The nutshell explanation...
when building filter queries from facet constraint values:
* {!field} works in a lot of situations, but if you are using an analyzer
on your facet field, there are some edge cases were it won't do what you
expect.
* {!raw} is truely raw terms, which works in almost all cases where you
are likely using facet.field -- but it's too raw for some field
types that use binary term values (like Trie)
* {!term} does exactly what you would expect/want in all cases when your
input is a facet constraint. it builts a term query from the human
readable string representation (even if the internal representation is
binary)
