How to find similar values in a field?

[templier]

Hello all!
I have a interesting question.
We have a next data:
Two field

a.tudhikova b-antuzh
a.rusevskaya    a_rusevskaya
a.rusevskaya    alishka92

How we can see a.rusevskaya and a_rusevskaya is similar
Question: can we make a request for matching similarity this field?
I understand that there will be errors in the definition, it's not critical.

try using the match command
http://docs.splunk.com/Documentation/Splunk/7.1.2/SearchReference/ConditionalFunctions#match.28SUBJE...

|eval similar=if(match(col2,col1),1,0)

here is sample code using your data above

|makeresults|eval data="col1='a.tudhikova',col2='b-antuzh' col1='a.rusevskaya',col2='a_rusevskaya' col1='a.rusevskaya',col2='alishka92'"|makemv data|mvexpand data|rename data as _raw|kv|rex mode=sed field=col1 "s/'//g"|rex mode=sed field=col2 "s/'//g"|eval similar=if(match(col2,col1),1,0)

@cmerriman hi.
In testing have a trouble:
Have a two address:
a.krikun - akrikunart

And this couple is not similar. Can we modify regex?

[cmerriman]

You could add an OR statement in the if statement. Haven’t tested that myself yet, though.

|eval similar=if(match(col2,col1) OR match(col1,col2),1,0)

I test it - not work.
We have the are many email log from users. And we want see when user send mail to personal email. Very often they are using similar address, few in example in first post, and one more:
v.anasimova - anasimova.v.s
