Add Problem/Resolution to query problem using the query plan

Adding content that could be used for query problem resolution. The initial attachment does the following:

• states the query problem (i.e., not pushing down the "IN" clause)
• provides the query plan (and debug log) for the query being submitted
• provides recommendations for resolving the problem
• then indicates how this problem was resolved and what the resulting query plan / debug log

The idea here is to continue to add other problem scenarios so that this information is really useful for resolving issues.
