When I search for lemma:βούλομαι@V?M in the NA27 Greek New Testament, I get 0 results, even though most instances of this verb are tagged as middle or middle/passive.
A search for passive returns only 4 instances (all
aorist passive). The search misses the instances where this verb is tagged as middle/passive. So somehow the search engine is failing to find the
middle forms of βούλομαι and the passive forms where the tag is middle/passive. It seems to work for other verbs I have tested at
random, such as lemma:ἔρχομαι@V?M, although I have not checked it to see if all matches are returned.
A search for middle of βούλομαι in the Gramcord text works fine (32 matches). They classify 5 instances as passive (2 Pet 3:9 is an odd classification, since it appears is translated as middle by most English versions). But nevertheless the search works correctly.
I would expect that if the word was tagged middle/passive, a search for middle would find the word as well as a search for passive. That is the advantage of double tagging the voice.
