facet.iPrefix : this would act like case-insensitive search. (or --->
facet.prefix=a&facet.caseinsense=on)

I don't see a reason as to why the case filter be there. you can always apply a
lower case filter to you field while indexing and searching.
{quote}
facet.regex : this is pure regular expression search (which obviously would be
expensive if issued).
{quote}
You mean wildcards. Right?

Moreover, allowing multiple filtering for same field would be great like
facet.prefix=a OR facet.prefix=A ... sth like this.

This has been recently discussed on the dev mailing list here -
http://www.lucidimagination.com/search/document/f954dbb323746ed1/multiple_facet_prefix
The syntax that was agreed upon was local params in this manner -
facet.field={!prefix=foo prefix=bar}myfield
> Add more search options for filtering facets.

> URL: https://issues.apache.org/jira/browse/SOLR-1387
> Project: Solr
> Issue Type: New Feature
> Components: search
> Affects Versions: 1.4
> Reporter: Anil Khadka
>
> Currently for filtering the facets, we have to use prefix (which use
> String.startsWith() in java).
> We can add some parameters like
> * facet.iPrefix : this would act like case-insensitive search. (or --->
> facet.prefix=a&facet.caseinsense=on)
> * facet.regex : this is pure regular expression search (which obviously would
> be expensive if issued).
> Moreover, allowing multiple filtering for same field would be great like
> facet.prefix=a OR facet.prefix=A ... sth like this.
> All above concepts could be equally applicable to TermsComponent.
