WanyWord is all you need if you want to both the haystack and the needle and want to search for words within a sentence, a line or a page.

If you want to study the Bible or Shakespeare, there are CD-ROMs with search programs. But those programs can only be used for the text(s) on those CD-ROMs. WanyWord can be used for any text anywhere and by anybody. There are no copyright problems. Schools and libraries with small or nonexistent budgets may therefore find it of interest.

Also if the database program you use to store odds and ends is not quite what you want, WanyWord is worth a look. A number of freeform database programs can store odds and ends, the problem is that they assume that you think and work like the programmers who wrote them. If you do, look no further, you are in luck.
