Is there a way to limit the number of results returned in a search from the getInputData stage of a MapReduce script?

You can use the

formulanumeric

formula; `

search.createFilter({name: 'formulanumeric', operator: 'lessthan', formula: 'rownum', values: '75001'})

Nothing native that can do that. You'd have to manually limit results inside the getInputData function.

return search.load({id: 1234}).run().getRange({start:0, end: 1000})

will get you the first 1000 if you’re looking for a quickish fix. otherwise yeah, a bigger getInputData function to run the search and build up an array
