Description

csw:AnyText - Chinese+digital content query doesn't return expected records.

using csw url syntax below:

http://localhost/pycsw?service=CSW&version=2.0.2&request=GetRecords&typeNames=gmd:MD_Metadata&resultType=results&elementSetName=full&Constraint=csw:AnyText%20like%20%27%%E6%A0%87%E9%A2%98%%27&constraintLanguage=CQL_TEXT
