Censys expands queries to provide additional functionality. For example, the query a:zmap.io
executes a DNS lookup and expands to ip:184.108.40.206.
Your query was changed from:
parsed.tbs_noct_fingerprint: 0625ac65b521da9255c15c0b806e2a3c90d010b0cdc7045df65d05f5cb693db9 and precert: true
parsed.tbs_noct_fingerprint: 0625ac65b521da9255c15c0b806e2a3c90d010b0cdc7045df65d05f5cb693db9 AND precert: true
If this isn't what you intended, you can run your raw query without expansion.
