No. We’re only searching for life in a tiny area around the Sun within our galaxy, the Milky Way. To find life we first need to find planets, which involves looking at stars over extended periods of time to detect tiny dips in brightness (transit method) or tiny wobbles causing minute redshift-blueshift cycles (doppler shift method).
Those cosmic filament structures are on the scale of millions and billions of galaxies over distances far larger than the size of a single galaxy. We can’t even resolve individual stars beyond our Local Group of galaxies and still most of the stars within the Milky Way are too far to use our exoplanet detection techniques (2 of them mentioned previously).
Finally, to search for life we’ve been attempting to search for spectral absorption lines of the gases in the atmosphere of an exoplanet, which involves recording a spectrograph during the transit method. This only works for stars with their orbital planes edge-on to us so that we can actually detect the planetary transits and record enough light from them over time to see how the spectrograph changes during the transit events.
