Search Form 2.0 is a good place to start.
Much more in depth is the Access Search Seminar

To be honest though we need more information on the structure of your db an tables to go much farther.

thanks for the link, it really looks like something I must do

there is one table with just over a 1000 articles (rows) i.e. the text of the article is stored in a Long Text

there is another table there are 70 keywords stored in short text each in their own row

trying to search those keywords against the articles table and only have a result that contains a row which contains article text matching the keyword

It is actually a little difficult to search Long Text fields.  
In my mind your best bet is to set up a third Junction Table and relate the Article Record(s) to the Keyword Table.
That type of relationship is called a Many-to-Many
By your description I'm guessing that you could have one keyword related to many articles and one article could have multiple (or no) keywords.

If you are not familiar to Relationships check out this video first.

I see that at this point in time you don't have any of the courses under your belt so I don't know what your experience level is in order to point you to specific courses.  The best way would be to start t the beginning and don't skip levels any way.

thanks, I just started working on a junction table as had the same thought along the lines of the many to many relationship exactly based on what you mention "could have one keyword related to many articles and one article could have multiple (or no) keywords".

I actually did several of Richard's courses some years ago and been using access since Windows 95 on a casual basis, have some idea to get by.

Thanks again let me try this

Just some feedback, got it to work, but it is not pretty, the result is massive, but in case anyone else has a similar issue.

Tables were ArticlesT and KeyWordT
Created a query with both tables and added the article row from ArticlesT and added the keyword row from KeyWordT
Wrote an expression Search: InStr([ArticlesT].[Article],[KeyWordsT].[keyword])

As mentioned, not pretty
