RAND has designed a searchable collection of jihadi fatwas, analyses, interviews, etc, called the "Voices of Jihad" database:
This online database is a compilation of speeches, interviews, statements, and publications of jihadist leaders, foot soldiers, and sympathizers. Nearly all content is in English translation, and has been collected from publicly-accessible websites. Original links are provided, along with excerpts and full-text content when available.
This is a search of the word "strategy." The database runs on Vivisimo a far more useful search engine than Google, because it organizes results based on concepts represented in the search results. The first hit is the strategy paper thought to have inspired the 3/11 Madrid bombings, Jihadi Iraq: Hopes and Risks.
