Or if you want to use the standard feature sets, format your annotation like this

dam		|:1:SG:PF:-dat-|:GEN:PL:-dama-|

Then you can write the queries above using "contains" and "matches" operator, which ensures that your regexp only matches within one alternative:

	[annot contains ".*:GEN:.*"]

	[annot contains ".*-dama-"]

	[annot contains ".*:GEN:.*-dama-"]

	[annot matches ".*-dat-"]  # ensures that all analyses are forms of "dat" => no lemma ambiguity

Best,
