  Modified versions of two "standard" pulsar search techniques are presented
that allow large-scale searches for pulsations in long duration high-energy
data sets using relatively modest amounts of computer time. For small numbers
of photons (N_phot <~ 10^4), optimized brute-force epoch folding searches are
preferred. For larger numbers of photons, advanced Fourier domain acceleration
searches are used. Using these techniques, my collaborators and I have searched
Chandra observations of the CasA supernova remnant (SNR) point source and the
isolated neutron star RX J1856.5-3754 for pulsations, and confirmed the 65.6 ms
pulsar in the 3C 58 SNR during a blind search of archival RXTE data.
