> Key: SOLR-6479
> URL: https://issues.apache.org/jira/browse/SOLR-6479
> Project: Solr
> Issue Type: Bug
> Components: query parsers
> Affects Versions: 4.9
> Environment: Java 7
> Linux
> Reporter: Pierre Salagnac
> Priority: Minor
> Labels: patch
> Attachments: SOLR-6479.patch

>
> Before doing through the syntax parser, edismax does a pre-analysis of the
> query to applies some parameters, like whether lower case operators are
> recognized.
> This basic analysis in {{splitIntoClauses()}} pseudo-tokenizes the query
> string on whitespaces. An operator directly followed by a parenthesis is not
> recognized because only one token is created.
> {code}
> foo AND (bar) -> foo ; AND ; (bar)
> foo AND(bar) -> foo ; AND(bar)
> {code}
