Date Format Conversion Function Query
Dear all,
Hi,
I was wondering is there any function query for converting date format in
Solr? If no, how can I implement such function query myself?

Thank you very much.
It seems that document transformer is the perfect extension point for this
conversion. I will try to implement that.
Best regards.

Another technology that might make more sense is a Doc Transformer.
You also specify them in the fl parameter. I would imagine you could
specify
fl=id,[persian f=gregorian_Date]
See here for more cases:
https://cwiki.apache.org/confluence/display/solr/Transforming+Result+Documents
This does not exist right now, but would make a good contribution to
Solr itself, I'd say.

Erick will correct me if I am wrong but this function query I don't think
it exists.
But maybe can be a nice contribution.
It should take in input a date format and a field and give in response the
new formatted Date.
The would be simple to use it :
fl=id,persian_date:dateFormat("yyyy/mm/dd",gregorian_Date)
The date format is an example in input is an example.
Cheers

Re: Date Format Conversion Function Query

Dear Erick,
Hi,
Actually I want to convert date format from Geregorian calendar (solr
default) to Perisan calendar. You may ask why i do not do that at client
side? Here is why:
I want to provide a way to extract data from solr in the csv format. I know
that solr has csv ResponseWriter that could be used in this case. But my
problem is that the date format in solr index is provided by Geregorian
calendar and I want to put that in Persian calendar. Therefore I was
thinking of a function query to do that at query time for me.
Regards.

I'm not sure what you're asking for, give us an example input/output pair?
Best,
