Anil Khadka commented on SOLR-1387:
-----------------------------------
Thanks for finally pushing it into the code.
The 'contain' and 'contains.IgnoreCase' will cover most of the use-cases.
I remember during that time, the code I wrote performed just fine (not
terrible) for regular expression case. But mostly it was used for
auto-completion that didn't use regex and worked pretty good.
Directly using FSA (or FST), like in Lucene would be great for regex (and
interesting project!)
Thanks again guys.

> 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.
