Search Function Not Working - The connection was reset after adding 100000 new produc

I've been using ZenCart successfully for a number of years. Recently, my client used Easy Populate 4 to add ~150,000 new products to their store and since then whenever a search is done with keywords that would need to scan all of those products at once, we get this: 'The connection was reset.'

I presume that the search is too taxing on our server (hosted by GoDaddy) and that it just can't query properly for some reason.

Any help with this would be great!
