Description

Allow $fetchrows as supplied to do_search() to support an integer or array. If integer then search will recieve the number of rows with no offset.
If array then search will receive the number of rows to return and an offset allowing for chunking of results.
$chunk_offset[0] is the offset of the first row to return. $chunk_offset[1] is the number of rows to return in the batch. $chunk_offset[0] will normally be 0 in the first search,
increasing by $chunk_offset[1] for each search, generated by an external looping structure. This allows for batches of $chunk_offset[1] search results up to the total size of the search.
For an example {@see pages/csv_export_results_metadata.php}. This approach can be used to avoid particularly large searches exceeding the PHP memory_limit when processing the data in ps_query().

Parameters

Column	Type	Description
$fetchrows	int\|array	$fetchrows value passed from do_search() / search_special(). See details above.
&$chunk_offset	?int
&$search_chunk_size:	?int
$chunk_offset	int	Starting position for offset. Default is 0 if none supplied i.e. $fetchrows is int.
$search_chunk_size	int	Number of rows to return.

Return

void
