# Test cases fts3defer-1.* are the "warm body" cases. The database contains
# one row with 15000 instances of the token "a". This makes the doclist for
# "a" so large that FTS3 will avoid loading it in most cases.
#
# To show this, test cases fts3defer-1.2.* execute a bunch of FTS3 queries
# involving token "a". Then, fts3defer-1.3.* replaces the doclist for token
# "a" with all zeroes and fts3defer-1.4.* repeats the tests from 1.2. If
# the tests still work, we can conclude that the doclist for "a" was not
# used.

# These tests - fts3defer-2.* - are more rigorous. They test that for a
# variety of queries, FTS3 and FTS4 return the same results. And that
# zeroing the very large doclists that FTS4 does not load does not change
# the results.
#
# They use the following pseudo-randomly generated document data. The
# tokens "zm" and "jk" are especially common in this dataset. Additionally,
# two documents are added to the pseudo-random data before it is loaded
# into FTS4 containing 100,000 instances of the "zm" and "jk" tokens. This
# makes the doclists for those tokens so large that FTS4 avoids loading them
# into memory if possible.
