Question

以下MarkLogic搜索正在进行区分大小写的搜索？如何使用以下代码段执行不区分大小写的搜索？

String optionsName = "PRODUCT_BY_TITLE";
String options ="&lt;search:options xmlns:search='http://marklogic.com/appservices/search'>"+         "&lt;/search:options>";

QueryOptionsManager qoManager = 
    client.newServerConfigManager().newQueryOptionsManager();
// create a handle to send the query options
StringHandle writeHandle = new StringHandle(options);
// write the query options to the database
qoManager.writeOptions(optionsName, writeHandle);

QueryManager queryMgr = client.newQueryManager();
KeyValueQueryDefinition kvqdef = queryMgr.newKeyValueDefinition(optionsName);
kvqdef.put(queryMgr.newElementLocator(new QName(ConstantsUtil.BIBLIOGRAPHIC_MSG_NAMESPACE_PREFIX+":"+elementName)), elementValue);              
JacksonHandle handle = new JacksonHandle();
queryMgr.search(kvqdef, handle);                
logger.info("response-->"+handle.toString());

安迪：

KeyValueQueryDefinition适用于最简单的情况。您的要求已逐渐变为更复杂的界面。

您可以使用StructuredQueryBuilder传递元素值查询的选项：

http://docs.marklogic.com/javadoc/client/com/marklogic/client/query/StructuredQueryBuilder.html

以下代码（未经测试）的某些内容应该有效：

StructuredQueryBuilder qb = new StructuredQueryBuilder(optionsName);
StructuredQueryDefinition queryDef = qb.value(
    qb.element(new QName(
        ConstantsUtil.BIBLIOGRAPHIC_MSG_NAMESPACE_PREFIX+":"+elementName)),
    FragmentScope.DOCUMENTS,
    new String[]{"case-insensitive"},
    1,
    elementValue);
JacksonHandle handle = new JacksonHandle();
queryMgr.search(queryDef, handle);
