On Windows with NTFS drives (networked or local), I use VoidTools Everything for instant as-you-type search results. It doesn't index contents of files, and for networked drives must periodic'ly re-index them, at moderate cost (compared to the heavier cost Windows Search when indexing /local/ drives). Also unlike Windows Search, it doesn't default to "search a few of the most common locations and either take a random number of seconds to realise at least one of the search targets was already displayed in the current folder where you started your search or claim that nothing was found (when one or more actually matches exist)".
