Hoss Man updated SOLR-4481:
---------------------------
Attachment: SOLR-4481.patch
Patch for review (includes docs & tests).
some example usages straight from javadocs...
{noformat}
In the examples below, the result of each query would be XXX....
q = {!switch s.foo=XXX s.bar=zzz s.yak=qqq}foo
q = {!switch s.foo=qqq s.bar=XXX s.yak=zzz} bar // extra whitespace
q = {!switch defSwitch=XXX s.foo=qqq s.bar=zzz}asdf // fallback on defSwitch
q = {!switch s=XXX s.bar=zzz s.yak=qqq} // blank input

A practical usage of this QParsePlugin, is in specifying "appends" fq params
in the configuration of a SearchHandler, to provide a fixed set of filter
options for clients using custom parameter names. Using the example
configuration below, clients can optionally specify the custom parameters
in_stock and shipping to override the default filtering behavior, but are
limited to the specific set of legal values (shipping=any|free,
in_stock=yes|no|all).
{code}
<requestHandler name="/select" class="solr.SearchHandler">
<lst name="defaults">
<str name="in_stock">yes</str>
<str name="shipping">any</str>
</lst>
<lst name="appends">
<str name="fq">{!switch s.all='*:*'
s.yes='inStock:true'
s.no='inStock:false'
v=$in_stock}</str>
<str name="fq">{!switch s.any='*:*'
s.free='shipping_cost:0.0'
v=$shipping}</str>
</lst>
</requestHandler>

> Inspired by a conversation i had with someone on IRC a while back about using
> "append" fq params + local params to create custom request params, it
> occurred to me that it would be handy to have a "switch" qparser that could
> be configured with some set of fixed "switch case" localparams that it would
> delegate too based on it's input string.
