Re : AW: How to select all docs of 'today' ?

Thanks it works.

 All this is based on the fact that NOW/DAY means the beginning of the day.

 Hi, "fetch-time:[NOW/DAY TO NOW]" should do it. Best Sebastian -----Ursprüngliche Nachricht----- Von: Danicela nutch [mailto:Danicela-nutch@mail.com] Gesendet: Dienstag, 22.

I want to make a query to get all documents fetched today. I tried : fetch-time:NOW/DAY but it returns always 0. fetch-time:[NOW/DAY TO NOW/DAY] (it returns 0) fetch-time:[NOW/DAY-1DAY TO NOW/DAY] but it returns documents fetched yesterday. fetch-time:[NOW/DAY-1HOUR TO NOW/DAY] but it's incorrect too. Do you have any idea ? Thanks in advance.

One subtlety to note is that caching is messed up by this form
since NOW evaluates to the second, and submitting two
successive queries exactly like this won't re-use the cache. On
a query like this it may not matter unless you're paging....

But on filter queries, its a good habit to cultivate to write
something like
[NOW/DAY TO NOW/DAY+1DAY]
which will be reused until midnight tonight.......
