String Search and the LIKE condition
Like operator allows you to pick only the domains that are "like" whatever you specify. The percent sign "%" is used as a wild card to match any possible character. For example:
[Domain] LIKE 'net%'
Will select all domain names starting with "net". Examples include netnames.com, netnames.org, etc.
[Domain] LIKE '%net%'
Will select all domain names that contain the word "web" anywhere. Examples include netnames.com, mynetname.com, domain.net, etc.
[Domain] LIKE '%net'
Will select all domain names that end with "net". Examples include myname.net, domain.net, etc. However, this will not find domains like mynet.com, skynet.org, etc.
[Domain] LIKE '%net.%'
Will select all domain names that contain "net." (without the quotes). Examples include mynet.com, skynet.org, etc.
Multiple Conditions using AND or OR
You can combine multiple conditions like so...
[Domain] Like '%soft%' OR [Domain] Like '%comp%' AND [Domain] Like '%.com'
... to find domains that contain the words "soft" or "comp" and end in ".com".
