> edismax lowercaseOperators=false broken by SOLR-3026

> Key: SOLR-3453
> URL: https://issues.apache.org/jira/browse/SOLR-3453
> Project: Solr
> Issue Type: Bug
> Components: search
> Affects Versions: 3.6
> Reporter: Michael Ryan
> Fix For: 4.0, 5.0

> The edismax lowercaseOperators=false option seems to have been broken by
> SOLR-3026. "foo and bar" and "foo or bar" are treated as "foo AND bar" and
> "foo OR bar", respectively, even when lowercaseOperators=false.
> Fix is rather simple, I think (though I haven't tested this). Current code:
> {noformat} if (i>0 && i+1<clauses.size()) {
> if ("AND".equalsIgnoreCase(s)) {
> s="AND";
> } else if ("OR".equalsIgnoreCase(s)) {
> s="OR";
> }
> }{noformat}
> Proposed code:
> {noformat} if (lowercaseOperators) {
> if (i>0 && i+1<clauses.size()) {
> if ("AND".equalsIgnoreCase(s)) {
> s="AND";
> } else if ("OR".equalsIgnoreCase(s)) {
> s="OR";
> }
> }
> }{noformat}
> Also interesting is the treatment of "Or" and "oR", but I'll leave that as an
> exercise to the reader.
