Read data between in log file based on date

Hi,

I have a log file and want to read everyday data only.
File Format is like

Somedata

I want to read data from previous day to current day. Is is possible ? Please suggest.
E.g. in above file,
I want to read data between March 9 to March 10
Next Day, I want to read from March 10 to March 11
and so on

Is it possible to achieve? Please suggest.
Thanks,
AXS

Relative time windows is the solution. But it does not make much sense, how can you read logs from today if the day is not finish?

| search earliest=-@1d latest=+@1d 

You should instead

| search earliest=-1d

Splunk reads whole file everyday and it can lead to increase in DB size.
I want Splunk to only data between current and next day date from log file.

No like first Splunk whole file and do indexing and then it give me one day data.

How often the file is updated, real-time or once a day??

[axs21]

The file is updated on realtime.
Another thing is splunk reads whole file but I want Splunk to read data only from current date and to next date from log file.

Is the data from this file indexed into Splunk? What dictates an event break - each new line? Or is this data in a lookup file?

Each new line dictates an event break
