thanks a lot
but i have another same question
when i want to search some text in all my note(the text property of note
NOT the name of note) and group the result by the "name property" and look
like the before question i want to know the count of each group what to do?
in sql something like this :
select count(*),name from notes when text like '%cat%' group by name;
my code like this:
NSString *text = @"cat";
CBLView* view = [database viewNamed: @"fullTextSearch_on_note"];
if (!view.mapBlock) {
[view setMapBlock: MAPBLOCK({
if ([doc[@"doc_type"] isEqualToString: @"note"]) {
id date = [doc objectForKey: @"created_at"];
NSString* body = doc[@"text"];
//emit(body,@[date,doc]);
emit(CBLTextKey(body),@[doc["name"],date]);
}
}) reduceBlock: REDUCEBLOCK({
return @(values.count);
})
version: @"5"]; // bump version any time you change the
MAPBLOCK body!
}
CBLQuery* query = [view createQuery];
query.fullTextQuery = text;
query.groupLevel = 1;
NSError *err;
CBLQueryEnumerator *allDocument = [query run:&err];
but the row of allDocument is zero (no result)
