# A boolean chart is a way of representing the terms in a logical
# expression. Bugzilla builds SQL queries depending on how you enter
# terms into the boolean chart. Boolean charts are represented in
# urls as tree-tuples of (chart id, row, column). The query form
# (query.cgi) may contain an arbitrary number of boolean charts where
# each chart represents a clause in a SQL query.
#
# The query form starts out with one boolean chart containing one
# row and one column. Extra rows can be created by pressing the
# AND button at the bottom of the chart. Extra columns are created
# by pressing the OR button at the right end of the chart. Extra
# charts are created by pressing "Add another boolean chart".
#
# Each chart consists of an artibrary number of rows and columns.
# The terms within a row are ORed together. The expressions represented
# by each row are ANDed together. The expressions represented by each
# chart are ANDed together.
#
# ----------------------
# | col2 | col2 | col3 |
# --------------|------|------|
# | row1 | a1 | a2 | |
# |------|------|------|------| => ((a1 OR a2) AND (b1 OR b2 OR b3) AND (c1))
# | row2 | b1 | b2 | b3 |
# |------|------|------|------|
# | row3 | c1 | | |
# -----------------------------
#
# --------
# | col2 |
# --------------|
# | row1 | d1 | => (d1)
# ---------------
#
# Together, these two charts represent a SQL expression like this
# SELECT blah FROM blah WHERE ( (a1 OR a2)AND(b1 OR b2 OR b3)AND(c1)) AND (d1)
#
# The terms within a single row of a boolean chart are all constraints
# on a single piece of data. If you're looking for a bug that has two
# different people cc'd on it, then you need to use two boolean charts.
# This will find bugs with one CC mathing 'foo@blah.org' and and another
# CC matching 'bar@blah.org'.
