To include a regular expression in a comma-separated list of query conditions for the field, use the$regexoperator. For example: copy copied {name:{$regex:/acme.*corp/i,$nin:['acmeblahcorp']}}{name:{$regex:/acme.*corp/,$options:'i',$nin:['acmeblahcorp']}}{name:{$regex:'acme....
For example, using the regular expressionre.split()method, we can split the string either by the comma or by space. With the regexsplit()method, you will get more flexibility. You can specify a pattern for the delimiters where you can specify multiple delimiters, while with the string’ssp...

The next part of the input is 2 digits or the string "N/A." To match that, we need to use a feature called alternatives. Alternatives match one of two or more subexpressions, with each alternative separated from the others by |. Here's how it looks: ...
