Subject: Two changes:
X-Git-Url: https://old-git.evergreen-ils.org/?a=commitdiff_plain;h=6587a4baccb03f5450c9ad11c3b7161e1b5bff40;p=working%2FEvergreen.git

Two changes:

    1) move canonicalization stuff into O/A/Storage/QueryParser
    2) no longer require config (filters, operators, etc) to be passed
        in with query to canonicalize
