Hi Koji,
Thank you. I implemented a solution based on the FieldTermStackTest.java
and if I do a search like "iron ore" it matches iron or ore. The same is
true if I specify iron AND ore.
The termSetMap[0].value[0] = ore and termSetMap[0].value[1] = iron.
What am I missing in having a prhase match correctly?
Thanks,
Steve

So you want to access FieldTermStack, I understand.
The way to access it, I wrote it at previous mail:
