Thanks. So, after I've travelled to Seattle to get my coffee, do you think
that creating this index will speed up the select queries?
Would it be faster if I had created separate tables and indexed them
individually?
What is the thoughts about searching text fields for text. Is it best to
store the text in a text field or is it best to tokenize out the terms and
create a word table with index?
Thanks
David
