searching for credit card numbers

[alex135]

Sorry if this is a newby question but I'm just getting started with the search appliance.

We are trying to find a way to search for major credit card numbers within documents. I created a test doc with bogus numbers for the major card companies.

Added that file to our test data set and waited for the box to crawl the file.

Once i confirmed the file has been crawled i used this string to search fro the numbers


/[1-9]{3}\-=[0-9]{2}\-=/[0-9]{4}\

which i found in the texis help but can no longer find.

Anyway, the box returns 'query not indexable'. I would like to know why the query won't work.

Thanks,

i just realized that i copied the incorrect string into my post...

here's the one i meant to send


/[1-9]{4}\-=[0-9]{4}\-=/[0-9]{4}\-=/[0-9]{4}\

sorry for any confusion

You're asking for a "regular expression" match. Those can't take advantage of an index so must search linearly through the raw data which can be slow. There are search options to allow linear searching but in general it's better if there's some other indexable term that can be added to the query to reduce the number of records that require linear searching.

Also, your expression doesn't seem right. Perhaps you want something like
/[0-9]{4}-=[0-9]{4}-=[0-9]{4}-=[0-9]{4}
Note that amex uses a different format than most others and won't match that expression.
