WASHINGTON — The instructions that Internal Revenue Service officials used to look for applicants seeking tax-exempt status with “Tea Party” and “Patriots” in their titles also included groups whose names included the words “Progressive” and “Occupy,” according to I.R.S. documents released Monday.

The documents appeared to back up contentions by I.R.S. officials and some Democrats that the agency did not intend to single out conservative groups for special scrutiny. Instead, the documents say, officials were trying to use “key word” shortcuts to find overtly political organizations — both liberal and conservative — that were after tax favors by saying they were social welfare organizations.

But the practice appeared to go much farther than that. One such “be on the lookout” list included medical marijuana groups, organizations that were promoting President Obama’s health care law, and applications that dealt “with disputed territories in the Middle East.”

Taken together, the documents seem to change the terms of a scandal that exploded over accusations that the I.R.S. had tried to stifle a nascent conservative political movement. Instead, the dispute now revolves around questionable sorting tactics used by I.R.S. application screeners.
