Notes are available in almost any module/part of the program. In theory this is one big table in the backup, while it binds each note specifically to a single row / entry in the asset database.
In general do notes help a lot, just imagine any special configuration on a workstation or server, special occurrences, history information – what ever you want and are able to in a text form you can save as a note to assets, purchases, software, employees, you name it. This eventually leads to a way more thorough documentation.
Of course, all, those scattered notes are only helpful if you touch the specific module and record and check if it has notes attached.
This was bypassed with a generic notes search. This allows you to search through all notes and then see on which type of entry (e.g. workstation) the note was added and an unique asset identifier like the asset tag of the workstation, while you are search full-text in the note entries.
