Description

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.
