Unhandled error causes other error later (update docs)

After updating from previous versions, now the index is built, but when querying i was getting this error on file search-index-searcher/lib/ScoreTopScoringDocsTFIDF.js:30

/home/.../javascript/website/node_modules/search-index-searcher/lib/ScoreTopScoringDocsTFIDF.js:30
            vector[field + sep + token] = docVector[token]
                                                   ^
TypeError: Cannot read property 'fiscales' of undefined

    at /home/.../javascript/website/node_modules/levelup/lib/levelup.js:222:14

But this error comes because other previous unhandled error on line 27, which has a nice comment about that:

err // TODO something clever with err

The error is:

ERROR NotFoundError: Key not found in database [DOCUMENT-VECTOR￮/book/impresoras-fiscales￮title￮]

@fergiemcdowall looking slowly to your code, i’ve found ’ ve missed the on('data', ...) handler on my code. Adding that solves my indexing problem!

So, i must note that the API docs are missing that required handler when feeding the streamer. Could u add that?

Good point- just updated it
