Best practices to debug Solr search in production without all
fields stored
Hi everyone,
I found it convenient to debug Solr search results if I mark all fields to be
"stored=true" in schema.
For example, given a document, I could check why it is not returned in a query
with debug=true.
But in production, most of the fields have "stored=false" for performance
reason.
I am wondering what would be the recommended approaches to easily reason Solr
search results if some used fields are not stored?
Thanks!

Are you trying to examine an individual document or some sort of bulk?
I sometimes facet on a field because that gives me the indexed
representation of it. There is also Luke to look at the raw index if
you want to really dig in.
Regards,
Alex.

For this specific case, you can use explainOther=id:<your unique key>
That will return the debug data for whatever ID you specify even if it
is not a hit. This is most useful when the reason is that the doc
didn't score high enough.
It can be somewhat unhelpful if you don't have terms that match since
it returns "0.0 = no matching term".
Best,
Erick

Here is a trick fl=field(color). It either hit docvalues, or swallow plenty
of heap for field cache uninvertion.
