Function Find-DbaDatabase
{
<#
.SYNOPSIS
Find database/s on multiple servers that match critea 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 a more detailed view showing regular output plus Tables, StoredProcedures, Views and ExtendedProperties to see they closely match to help find related databases.
