Neil,

Not translated to english. It's will be probably a part of the updated 
handbook in a few months.

The Visual Designer does not yet accept like 'abc%'  expressions. As a 
workaround I propose (just in this case) to use SQL View and enter SQL 
condition like:

"SELECT owner FROM cars WHERE cars.model LIKE 'Ford%'
                         ^^^^^^^^add this^^^^^^^^^^^^^^

Notes:
- "Check query" command will accept the condition
- being in the SQL View, save the query
- Do not switch back to the Visual Designer View, but switch _directly_ to 
data view - you will get your result; otherwise it will be screaming about 
'invalid expression' and you can lose the condition by saving the query in 
this mode
- LIKE operator in SQLite (file db) is case-sensitive unlike MS Access, the 
same for mysql (by default). We'll probably work to make that case-insensitive 
in for most db backends.

In 0.9 this didn't work and in 1.0 we decided to hide this. Will be 
implemented in 1.1. The plan is that you can e.g. select a numeric column, 
change 'totals' to SUM to see a groupped and summed query result. Read help 
for GROUP BY and SUM keywords, e.g. in any SQL handbook for more info.
