Jan H=C3=B8ydahl commented on SOLR-4646:
-----------------------------------

Tested this with Solr3.5 and it seems the default has been "true" all the w=
ay. Although I have not hit concrete problems due to this I always thought =
it defaulted to false.

Anyone else in favor of changing the default to "false" from v4.3? We could=
 check luceneMatchVersion to keep old default for pre-4.3 solrconfigs...

> *lowercaseOperators*
> This param controls whether to try to interpret lowercase words as boolea=
n operators such as "and", "not" and "or". Set {{&lowercaseOperators=3Dtrue=
}} to allow this. Default is {{"*false*"}}.

 off {{mm}} parameter:
