Uwe Schindler updated SOLR-5707:
--------------------------------
Attachment: SOLR-5707-allowdollar.patch
I just modified the Javascript parser to accept {{$}} as character inside
identifiers (was quite simple, because the $ sign has no other meaning in
Javascript). This is maybe an idea for another issue, I just posted it here as
patch, if we want to go this route.
According to the ECMAScript official documentation is the parser already too
strict, because ECMAScript allows all UnicodeLetters as ID characters, too. The
ANTLR parser only allows 'A'-'Z' and 'a'-'z' in addition to our special
characters.
