I am having a dumb tgrep problem that I'm hoping someone else might have run into. I'm trying to specify 'does not (immediately) dominate.' However, I keep getting messages saying "Event not found" with respect to the dominance or immediate dominance operator.
If I don't negate the dominance/immediate dominance operator, everything is fine. Thus:
babel>tgrep 'ADJP < CC' | more
(ADJP (VBG increasing)
(ADJP (RB so)
babel>tgrep 'ADJP !< CC' | more <: Event not found
I've tried this with single quotes and double quotes--no difference. I've also tried it with the precedence operator--same pattern.
