function Find-DbaDatabase {
    <#
        .SYNOPSIS
            Find database/s on multiple servers that match criteria you input
 
        .DESCRIPTION
            Allows you to search SQL Server instances for database that have either the same name, owner or service broker guid.
 
            There a several reasons for the service broker guid not matching on a restored database primarily using alter database new broker. or turn off broker to return a guid of 0000-0000-0000-0000.
 
        .PARAMETER SqlInstance
            The SQL Server that you're connecting to.
 
        .PARAMETER SqlCredential
            Credential object used to connect to the SQL Server as a different user
 
        .PARAMETER Property
            What you would like to search on. Either Database Name, Owner, or Service Broker GUID. Database name is the default.
 
        .PARAMETER Pattern
            Value that is searched for. This is a regular expression match but you can just use a plain ol string like 'dbareports'
 
        .PARAMETER Exact
            Search for an exact match instead of a pattern
 
        .PARAMETER Detailed
            Output all properties, will be depreciated in 1.0.0 release.
 
        .PARAMETER EnableException
            By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
            This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
            Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.
