DocumentsSearch functions (DocumentsSearch)

Use these functions to search document content and document properties.

To use this module in your Server-Side JavaScript code, include a require statement similar to following line in your code: 

const jsearch = require("/MarkLogic/jsearch");

The usage model for these methods is as follows: Create a document search builder using jsearch.documents, then chain calls to methods such as where and orderBy on the resulting object. Finally, execute the query by calling the result method.

The order in which you call the methods of this class is significant. You should preserve the order shown in the template below. For details, see Query Design Pattern in the Search Developer's Guide.

Use the methods of this class in the following way, where everything except the call to documents and result being optional. 

jsearch.documents()                         // creates a DocumentsSearch object
  .where(queries)
  .orderBy(jsonPropNamesOrIndexReferences)
  .filter()
  .slice(startPos, endPosPlusOne)
  .map(configOrFuncRef) | .reduce(configOrFuncRef)
  .withOptions(optionsConfig)
  .result()

For details, see jsearch.documents, DocumentsSearch, and Searching Documents in the Search Developer's Guide.
