  3. On the Workbench (Index Configuration) page, on the <\/span>Stages <\/b>column, click the <\/span>+<\/b> icon.<\/span><\/li>\n
  4. On the right column, select <\/span>Custom Script<\/b> from the <\/span>Stage Type<\/b> drop-down list.<\/span><\/li>\n
  5. Enter a name in the <\/span>Stage Name<\/b> field.<\/span><\/li>\n
  6. Enter a condition in the <\/span>Condition <\/b>field. \u00a0You can add multiple conditions using the AND\/OR connectors. Documents that satisfy the condition will be executed as part of the stage. See below for details<\/a>.<\/span><\/li>\n
  7. Under the <\/span><\/>Painless<\/b> section, enter the custom script. See below for details<\/a>.<\/span><\/li>\n
  8. Click\u00a0Simulate<\/b> to verify the configurations. The simulator displays the Source and the number of documents to which the mapping was applied, and the result. You can change the Source (if not mentioned in the condition) and the number of documents.<\/li>\n

    <\/span>Script<\/span><\/span><\/h3>\n

    Example<\/b><\/p>\n

    To copy a value from <\/span>“defaultAnswers[*].payload”<\/span><\/i> to<\/span> “answer[]”<\/span><\/i>, use the below script:<\/span><\/p>\n

    ctx.answer =[]; for (def item : ctx.defaultAnswers) { ctx.answer.add(item.payload) }<\/code><\/span><\/i><\/p>\n<\/div><\/div>

    <\/span>Conditions<\/span><\/span><\/h3>\n

    Condition is of the following format:\u00a0ctx.fieldtype==value<\/code>\u00a0or\u00a0ctx.fieldtype!=value<\/code>. The\u00a0field_name<\/em>\u00a0can be obtained from the Fields table under Index Configuration.<\/p>\n

    For example,\u00a0ctx.contentType==\"web\"<\/code>\u00a0to restrict the extraction to the content from a web source.<\/p>\n<\/div><\/div>
