+  The schema of the database is defined by HISTORY_URL_ROW_FIELDS found in
+  url_database.h and is equivalent to:
+
+  CREATE TABLE urls(id INTEGER PRIMARY KEY,
+                    url LONGVARCHAR,
+                    title LONGVARCHAR,
+                    visit_count INTEGER DEFAULT 0 NOT NULL,
+                    typed_count INTEGER DEFAULT 0 NOT NULL,
+                    last_visit_time INTEGER NOT NULL,
+                    hidden INTEGER DEFAULT 0 NOT NULL,
+                    favicon_id INTEGER DEFAULT 0 NOT NULL);
+
+  The quick history autocomplete provider filters out history items that:
+    1) have not been visited in kLowQualityMatchAgeLimitInDays, AND
+    2) for which the URL was not explicitly typed at least
+       kLowQualityMatchTypedLimit + 1 times, AND
+    3) have not been visited at least kLowQualityMatchVisitLimit + 1 times.
+  So we create history items in all of those combinations.
+
+  Note that the last_visit_time column for this test table represents the
+  relative number of days prior to 'today' to which the final column
+  value will be set during test setup. Beware: Do not set this number
+  to be equal to kLowQualityMatchAgeLimitInDays.
+
+  The ordering, URLs and titles must be kept in sync with the unit tests found
+  in in_memory_url_index_unittest.cc.
