Hi kids, I'm hoping that there's something I don't understand about the way views work. Lend me your brains. Is there any way to use the value of a reduction as part of the index?
So let's say we've implemented a word count. We have a nice view that is indexed by word, so we can query any word and find out how many times it appears. But if we want to know what words are the most frequent, seems to me that currently we're out of luck. The only way I can see to do it is to operate in multiple phases: ie, phase 1 would be updating the above query, and phase 2 would be writing the results of phase 1 into a different document type so that a subsequent mapping could emit(word_count, word). Hoping we can address this - all the classes of problems I want to solve with couchdb involve using the map-reduce algorithm for this type of multi-stage analysis. Ben
