[TECHNICAL-SUPPORT] LPS-32107 Make Custom Range inclusive in Search portlet to prevent IllegalArgumentException thrown by RangeFacet

Hi Zsolt,

There is a discussion about the problems I've discovered in Search Portlet at http://in.liferay.com/web/global.engineering/forums/-/message_boards/message/1077971

I'm sending this pull with minimum changes I could make to fix the original customer issue.

I have opened two more LPS tickets regarding the other issues: LPS-32233 and LPS-32255. I'm on to fix them as well, but it depends on my LPP load. 

Thank your for reviewing. Let me know if you have any notes.

Regards,
Tibor
