Can you expand your question a bit?
Do you want to compare the title fields in table A to Table B and if they exist
in both tables, display Table A records?
Do you want to look for a word (or words) in the title field of both Table A and
Table B and return all the records in both tables?
Do you want to look for approximate matches between the two tables? -- This can
be really, really tough to do depending on how you define approximate?
Is there some field in Table A that matches the data in a field in Table B?
Hopefully, if you can expand your question with some details (or a couple of
specific examples) then someone can give you an answer.
