api

FlumeViewSearch(version, minLength, map) => search

version is the view version. if this number changes to what is on disk, the index will regenerate.

minLength is the minimum word length to index. by default this is 3 letters.

map is a function that takes the document, and returns a string containing the text to be indexed.

search.query ({query, limit, keys, values}) => PullSource

create a pull-stream source of results for this query. query should be a string, and may contain multiple words. (words shorter than minLength are ignored) The order is in reverse chronological order.
