If @Taneb could take a looksie that'd be great!

The t -> [a] instance seems to work though:

>>> state^..wordData.withAny (toListOf folded . fetch AffixK) ["dor"].folded.word'
["donri"]

Although I'm not sure about withAll for that instance:

>>> state^.wordData.withAll (toListOf folded . fetch AffixK) ["dor"] & count
5911

Shoudn't withAll and withAny be equivalent when given a singleton list?

ekmett commented 11 years ago

They should be, yes.

It looks like the inverted indices are correctly set up for singleton tables, but they're empty for tables with more than one row. It also seems that withAny and withAll work correctly for singleton tables. This suggests to me that the problem likely is in either unsafeInsert or deleteCollisions (or both).

I'd like to investigate this issue but there is not enough context given in the report to reproduce the result myself. I know it's been quite a while since this issue was opened but if the reporter still has the code that produced this issue would they mind posting a more complete test case?
