Can't retrieve lastResults during searchFunction

Hi, I’m trying to use the previous search result to modify the search. While paused mid searchFunction, using the console I can see the previous results in search.helper.lastResult. However, when I try to access that within the function it is undefined.

Example returning undefined:

var instantsearchOptions = {
			searchFunction: function (helper) {
				if (helper.state.query === '' && !algoliaConfig.isSearchPage) {
				} else {;
                    console.log(search.helper.lastResults.query); \\ this throws Uncaught TypeError: search.helper is null

What am I missing?

The search.helper.lastResults object looks ok and has the info I want but the helper.lastResults object is null, hence why I am not trying to use that. Is there another way to access lastResults?
