What we really want is to ensure that any search is completely case-insensitive.
For example, apt.dat contains the following lines:
1 400 1 1 KLVK LIVERMORE MUNI
1 425 0 1 4AK2 Livengood Camp
1 3982 0 0 LIVD Dobbiaco
Currently, searching for "LIV" returns the first and last lines, while
searching for "Livermore" returns nothing, despite being what most people would
search for.
I think a use searching for "liv" would expect to see all the results above,
and more.
One issue that is worth discussion is that if we make the search completely
case-insensitive, we obviously increase the number of results returned.
In the example above, searching for "liv" would return a total of 54 results. A
much less unique string, such as "san" would return over 400.
Note that this assumes that the user has the entire world scenery installed,
which is pretty unlikely.
Nevertheless, I think these are acceptable numbers for a 3 character string.
The user can easily perform a more specific search on receiving a large number
of results.
I will continue looking at this, though if anyone else would like to jump in
with suggestions, that would be very welcome.
