Calculate occurences of phrase in Text Field Django

How can I filter my model MyModel on the basis of the number of occurences of a certain phrase in a text field in MyModel

I guess it can't be done with django orm, perhaps an SQL query can help?

Something like:

MyModal.objects.extra(count="SQL query that finds occurence count of a certain phrase in certain model field")

A complete raw query is fine too.


try this:

set @str='a b a c';
select length(@str)-length(replace(@str,'a','')) as 'number of occuarence'
