Michael, it's either a glossary that you optimise/maintain carefully or a memory in which you throw everything. You cannot use the memory approach for your glossaries.
Actually, this adding of terms/fragments to the glossary is something that requires constant attention/thinking/concentration/some automation and thoughts/policy and which is extremely satisfying. Both in linguistic perspective as in productivity outcome/performance.
And you'll find the optimisation features in the Glossary menu of great use.
