Censys expands queries to provide additional functionality. For example, the query a:zmap.io
executes a DNS lookup and expands to ip:22.214.171.124.
Your query was changed from:
parsed.tbs_noct_fingerprint: 3560e45b41e46b8f36537025d1d5bc02d9652a10645b0eff69e8b6a52191f335 and precert: true
parsed.tbs_noct_fingerprint: 3560e45b41e46b8f36537025d1d5bc02d9652a10645b0eff69e8b6a52191f335 AND precert: true
If this isn't what you intended, you can run your raw query without expansion.
