Find similar names using Couchbase server 3.0 and port 8092

问题

I want to find the similar location names using couchbase server. i created an index as follows

function (doc, meta) {
  emit(doc.loc_name, doc);
}

this is how i query data

http://IP Address:8092/dev-locations/_design/dev_test_view/_view/searchByLocationName?full_set=true&inclusive_end=true&stale=false&connection_timeout=60000&key=%22Joh%22

But this will return only if the exact match found. What i am looking for is when i send the key joh, it should return johenaskirchen and johenasberg (same as our LIKE in MySQL)

Any help will be highly appreciated.

Note : I already tried N1QL and i am looking for ways to implement this without N1QL

回答1:

the key parameter is an exact match. What you want is a combination of startKey and endKey:

?startkey=%22joh%22&endkey=%22joh\uefff%22

The \uefff is a trick, this unicode character can be seen as "the biggest character" so it ensures that a key like johzzzzzz will still be considered under the upper bound of joh\uefff (endkey is inclusive).
