Assuming this request is about exporting search results from the Find Tool, this is already supported. From the "hamburger" menu in the Find Tool, select "Record Set Options." This will bring up a screen that allows you select to add the search results to a new record set, as well as specify the name and owner of the record set. When these options are enabled, the record set bag icon in the Find Tool will appear green. Once you conduct a search with the options enabled, the first 10,000 results will be automatically added to the record set.

We are also adding support for Shift+Click to select groups of records in the Find Tool in Polaris 7.7, which will help if you need most but not all of the results.

I'm going to mark this idea as already supported, but please let me know if I've misunderstood the request.
