Search Hint #1 : If you know the registration number of the vehicle you're looking for, don't include manufacturer / model etc. in the search, as this may reduce your chance of success. If you've tried for specific reg and it isn't there, including more to the search like manuf/model will not help!

Search Hint #2 : Combine registration number and manufacturer / model etc. searches when you know only part of the reg, for example if you're looking for an 'S' reg Ford XR2, enter 'S' into the reg, choose the 'starts' option, then choose 'Ford' and enter XR2 in the model.

Search Hint #3 : When entering the Model / Type, be mindful that this data is entered by different owners in different ways, so less is probably more likely to find your vehicle, for example searching for 'Escort' will find more than 'Escort LX'.

Search Hint #4 : If you do a registration number search with 'Otherwise known as' included, this can contain strange data. So when you see results that don't seem to include the search you specified, it's because the match is in that field. (Ideally 'Otherwise known as' should include previous reg numbers for the vehicle, but often includes nicknames.)
