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

> 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.
