Basic proposition.

We are trying to use keywords to locate relevant essays.

Could I have a column which includes the keywords and within that
column I could do a search for those rows which possess all the
keywords?

ie

Each essay is allocated keywords by us.

Keywords could be:

speed, engineering, power etc etc etc

Could I then do a search on a column which could include those keywords
(in any order)? The resulting search would only show those relevant
rows.

Hope this makes sense.
