Hello Juan,
Please look at this documentation page: https://devcenter.appery.io/documenta...
Hi thanks. So, I assume indexed searches are out?
I can use a regex search, but I'll need a little help.
In my collection, I've got 2 columns, ColA and ColB (both are text columns)
I have 3 'keywords' e.g. "Coffee", "Tea" and "Ice".
I would like to do a query on the collection and have it return a result of all records where any (or both) of the columns contain any (or all) of the keywords.
Not sure what the regex query for this will look like.
Thanks
Ok, thanks.. In that case (no indexed search) please see my follow-up question below.
In this way you have to use "$or" parameter: https://devcenter.appery.io/documenta...
Ah thanks. What is the regex syntax to check for a string containing a substring.
StringA = "Coffee"
StringB = "The Coffee shop"
so basically a regex that will return 'true' when searching for the string "Coffee" in stringB.
Cheers
Please use simple strings for that:
{"$regex": "Coffee"}
and
{"$regex": "The Coffee shop"}
Hi There, it's about indexing a field in collection.
after creating the new collection
I inserted 2 columns. one of them I wanted it indexed, therefore I went to the "Index Manager" tab.
so far all fine.
then, comes my question: in my serverCode, shall I call that index again ?
I tried using
db.collection.ensureIndex({'columnName':1});
but got error msg cannot find undefined ... which means it does find the columnName ...
I m not to use this code if not necessary since the index is declared already.
what to do to make it effective ?
thks in advance,
Eric
Hello,
Please clarify, where did you found that code? What are you trying to do?
Hi Sergiy, I got that one there https://docs.mongodb.com/manual/refer...
maybe not necessary, since the indexed field does exist in the "manage index" tab ?
tell me,
best,
Eric
