Faceting return value of a function query?
Hi,
I'm new to Solr, and I'm having a problem with faceting. I would really
appreciate it if you could help :)
I have a set of documents in JSON format, which I could post to my Solr
core using the post.jar tool. Each document contains two fields, namely
"startDate" and "endDate", both of which are of type "date".
Conceptually, I would like to have a third field "timeSpan" that is
automatically generated from the return value of function query
"ms(endDate, startDate)", and do range facet on it, i.e. compute the
distribution of "timeSpan", among either all of or a filtered subset of the
documents.
I have tried to find ways of both directly faceting the function return
values and automatically generate the "timeSpan" field during indexing, but
without luck yet.
Suggestions are greatly appreciated!
Best,
Yubing

Turns out that update processors perfectly suit me needs. I ended up using
the StatelessScriptUpdateProcessor with a simple js script :-)

Yep. It's almost always easier and faster if you can pre-compute as
much as possible during indexing time. It'll take longer to index of
course, but the ratio of writing to the index to searching is usually
hugely in favor of doing the work during indexing.
Best,
Erick

Hi Erik,
Thanks for the reply! Do you mean parse and modify the documents before
sending them to Solr?
Cheers,
Yubing

Wouldn't it be easiest to compute the span at index time? Then it's
very straight-forward.
