You could certainly do this in REALbasic. A useful, free resource for
the dictionary etc would be WordNet <http://wordnet.princeton.edu/>.
But you're getting into some moderately complex stuff here. See, for
example: <http://citeseer.ist.psu.edu/context/20836/0> to see that
this is an area of active research for computer scientists. There are
standard approaches, though. Typical is to index all the substrings of
a particular length of each word, along with other information such as
in what order they occur. As you can imagine, the index can wind up
being many times the size of the original data.
Depending on your project, a compelling alternative might be Lucene:
<http://lucene.apache.org/java/docs/>. Lucene is very, very good at
this kind of thing.
OTOH, I'd love to see someone put together an all-REALbasic solution
for this. Extra bonus points if you implement an index that lets me do
grep searches. :-)
I just did a brute force inverted index with a very basic definition
for "word"
Basically gave me a pretty decent search and combined with a LIKE
clause was useful for my case
