I explained in my message that I wish to filter a list of names and
addresses dynamically when I type a name in a field. This list
contains 400'000 lines like this: Mme [TAB] DOS SANTOS albertina
[TAB] rue GOURGAS 23BIS [TAB] 1205 Genève
I made various tests using the "repeat for each" loop and the
"filter ... with" command. Filtering takes the most time when I type
the first and the second letter. That takes approximately 800
milliseconds for the first char and about 570 milliseconds for the
second char. The repeat loop with the "contains" operator is a little
beat slower (about 50 milliseconds) than the "filter ... with". There
is no significant difference when the third char or more is typed. Of
course I filter a variable before to put it in the list field.
Obviously, 800 milliseconds to filter a list of 400'000 lines, it is
fast. But it is too slow for what I want to do. It would take a time
of filtering lower than 300 milliseconds so that the user is not
slowed down in his typing.
Would it be practical to break your list into 26 sublists by first letter?
