Hi, Vinod: It's not an error to request more documents than exist.
Thus, in principle, you don't need to know in advance how many results exist. Theoretically, you could set the pageLength to the largest unsigned long to return a single response with as many results as possible. In practice, that will fail for any significant result set. Geert's recommendation will scale and perform much better.

Consider requesting multiple pages (with a pageLength of 100 for instance) (sequentially or maybe even in parallel) until you have gathered all results. Allowing to batch up the content will make your solution scale much better..

You could do one call with the pageLength set to zero. I believe this will still give you the total count of all records in the result -but no data. Then you could use that value to use for pageLenght. Not sure if there is a hard-coded max somewhere in the REST code. that would be the only hiccup, I believe.

We know that there is an attribute called “pageLength” to return the no of results to which it is set. But we want to return all documents from MarkLogic database without knowing its count. It’s not recommended to get all result in a single shot but currently our requirement is like that only. So, Is there any parametric value we have to pass in REST API search URL or any other way? Please suggest.
