The CDA Database can be particularly helpful for investigators and researches, as detailed here.
However, for investigators and researchers, a matter under inquiry can be relatively quick or it can sometimes take several days, weeks or even months.
Around 15-20,000 records get added to the database each day. Therefore, if an initial search is conducted at the commencement of a matter and then takes another say, 5 days to complete, up to 100,000 new records could have been added to the database during that time.
It can therefore be a good idea to not only conduct an initial search when your matter is started, but also to conduct another search when the matter has ended and before you provide your report.
Further, if you have an ongoing relationship with your client (e.g. a legal firm or insurance company for whom you do a lot of work), consider adding an Alert for that name. That way, should the name be added to the database at some future point, you can let your client know. This information might or might not be relevant at that point, but it demonstrates your ongoing support for your client's interests and promotes your professional approach to how you conduct your operations.
