regex - Negative Look Around in MongoDB Query -


for fields, uploaded. want make sure didn't corrupted (not mongo, data generator).

the field of interest take regex:

donor_\d{1,2}_\d+

for example:

donor_17_82635294

there no exception rule, wondering if use negative around in regex find fields don't meet rule. problem negative around examples on seems have know looking for, don't. want this.

db.collection.find({field:*not*/donor_\d{1,2}_\d+/i})

my other option create new collection matches regex, easier.

thanks j

yes can negation of regular expression this:

db.collection.find({field: { $not: /donor_\d{1,2}_\d+/i } })
