npm install norch and then start with norch

or programatically:

require('norch')(options, function(err, norch) {
  // Norch server started on http://localhost:3030 (or the specified host/port)
})

Put stuff in

curl -X POST -d @myData.json http://localhost:3030/add (where myData.json is a newline separated file of JSON objects)

Search for hits (uses search-index's API)

http://localhost:3030/search?q={"query":[{"AND":{"*":["usa"]}}]}

(http://localhost:3030/search returns everything)

Make autosuggest

http://localhost:3030/matcher?q=usa

Export, import, and replicate an index

# create a snapshot on the server (available under /latestSnapshot)
curl -X POST http://localhost:3030/snapshot
# get latest snapshot
curl -X GET http://anotherIndex:3030/latestSnapshot > export.json
# replicate an export file into a new index on another server
curl -X POST -d @export.json http://someOtherServer:3030/import
