Seeking a search engine or script

I’ve searched the forums and can’t find my question answered.
I produce a CD of Applegate family history and genealogy.
I make this CD available free to those who submit their Applegate family genealogy to me for inclusion in the database.
Presently there are over 5000 pages in MS Word format.
I need an imbedded search engine or script that can be added to the CD that will allow keyword, reference number, fuzzy or a boolean search.
I’m hoping one of you might be able to assist.
