Another angle to consider is using an external program via Valentin's
shell xtra:
http://staff.dasdeck.de/valentin/xtras/shell/
-- Welcome to Director -- (on macosx)
put shell_cmd("grep -i stringtofind /path/to/folder/*")
-- Welcome to Director -- (on windows)
put shell_cmd("find /I ""E&"stringtofind""E &" c:\path\to\folder\*")

Ross,
It depends on the size of your data. Director's text searching is
pretty fast. If you can load all of the text into a cast, you can
zip through it using "contains". Or you could do more complex stuff
with pregEx.
If it's not doable that way, then you could use a database and build
your own index. You scan all of the text once and store each
non-trivial word along with data describing where it is. Most
simply, you have a table with three columns:
word :: filename :: word_pos
Beyond that, you can also use functions built-in to your database
for searching text. I don't know if Valentina does this, but I'll
bet Ruslan will tell you if so.
Good luck,
Dave

Hi List
This is more of a general programming query than a Lingo-specific one.
I've been asked to build a search facility into a project. I'm
ashamed to admit it, but it's been many many years since I did any
programming outside of the multimedia-focused stuff of Director and
Flash and I'm totally stumped now on how to achieve this.
From what I can remember, it's going to be easier to index the contents of
these text files and then search this index instead of going
through all the files every time I perform a search. Trouble is
though I have no idea where to begin, how indexing really works and
thus how to go about it.
Enlighten me on the concepts so I know where to start and I can
take the Lingo from there!
TIA
