From APL Consultants of Houston:
Make an HTML file of contexts surrounding key words and phrases excerpted from a directory structure. While search engines just return links for you to continue following, phraSEarch follows its links and constructs a meaningful document that contains every context in which your search words and phrases were found. With its interface, you can create browseable HTML pages with as much context as you want, preceding and following your search words and phrases, built from documents on your local or LAN disk drives. Each context has highlighting of any words of your choice and a link to its original document. Whether your research field is medicine, law, theology, education, genealogy, military, history, science, journalism, or home schooling -- whether your research is from e-books, professional journals, recipes, movie guides, e-reference books, hobbies, or your personal documents -- phraSEarch is your off-line browsing companion of choice for compiling and summarizing information.
