Faceting question

[cricdigs]

I've been struggling with this a bit so here goes:

I'm using faceting to get some results. I also want to get another field -
the id field along with it. Is it possible to get that somehow in the facet
results?

Thanks!

: results?

you're going to have to elaborate on what it is you are trying to do ... i
genuinely have no idea what you are asking (and i think i'm usually pretty
good at reading between the lines and guessing what people mean).

You mean, when it says that facet term "foo" has 10 documents, you want
those 10 ids? I think that will require a further query from your
application.

lol I agree with you Hoss - sorry for that

Here's the thing:
I need additional information from the index - such as the id related to a
facet field. For example, say I am faceting on author names for a book
store, I would also like to get the author id along with the author name to
show a link (next to the author name) to say the author's bio page. The
author id is stored in the index but how do i get that back with the facet
results?

Faceting works on the terms in an index, so you can't get information
beyond those terms without doing extra work. You could build an extra
index used only for faceting that concatenates the information you need
from other fields, and then parse it out in your application: e.g.
"Tolkien, J.R.R.|35421".

If you're doing this so that you can do precise follow-on searches,
though (where a user clicks on a link in a list of facets), you might
want to think about whether the author name gives you everything you
need. You may have two authors with the same name, who would show up as
a single facet if you don't tack the id on; but even if you do, how is
the user going to distinguish them? They'll just see two links, maybe
with opaque id numbers. So maybe the bare author name is good enough. (I
had a similar situation and found that getting away from a
relational-database approach and going with what Solr does best was the
best solution).

Hope that helps,

Peter

Thanks Peter. That will be my work-around, but I was hoping to find a more elegant solution ;)
I am not that knowledgeable about the solr architecture but if there is a way it can be done in a more elegant way I might be willing to put the extra time to code it..

Hey, that's the shift in outlook I was talking about: if this were
MySQL, that would be a work-around; in Solr, building multiple indexes
for special purposes IS the elegant solution! (Though creating a new
fieldtype that does the concatenation automatically from two or more
other fields, like a copyfield, would be nice). Any other approach will
probably cut drastically into Solr's amazing speed at generating facets,
since it will require touching the documents or other indexes at query
time.
