When connecting to OBVSG SRU-Server, the generated GET Url contains maximumRecords=0, so no result is delivered. URL catched with tcdump looks like: https://services.obvsg.at/sru/OBV-LIT?version=1.2&operation=searchRetrieve&query=alma.isbn%3D%229783551354013%22&startRecord=1&maximumRecords=0&recordSchema=marcxml There is no possibility to change maximumRecords. This only occurs with this specific Server. It works flawlessly with services.dnb.de. One difference is: OBVSG only accepts connections via https, dnb via http. Is there a possibility to add the maximumRecords-Parameter to the admin Interface? Thank you!
