GNU Bool project is a utility for finding files that match a boolean expression.
The boolean operators supported are AND, OR and NOT. Also supported is the NEAR operator for locating two expressions within a short distance from each other.
The text processing algorithm understands that newlines don't always mean the end of a sentence. Therefore, the string "afternoon sun" matches "afternoonnsun" (notice the newline) because adjacent lines are assumed to be in the same context. On the other hand, two newlines would not match because they normally indicate a new paragraph which means a different context. The dash character is also supported to separate words before a newline, so the string "after-nnoon sun" would match.
The HTML processing algorithm understands many features of the HTML 4.01 standard. Entities such as é are supported in decimal as é or in hexadecimal as é. Elements also retain their structural meaning where the string "daytime" matches "< b >day< /b >time" because the bold text style does not separate words. On the other hand, "< p >day< /p >< p >time< /p >" does not match because paragraphs separate context.
