[opencms-dev] Filter search by date

[Alessandro Magnolo]

Hello Shi,
Thank you for your help.
I did everything you said, now the question is: I do I query the updated index?
In other words, now that I have the dates in the index, how do I get
for example the documents modified today?

Best regards,
Alessandro
