Hi Jay,
It's great that you have the opportunity to attend the training.
Coming back to your original question to Grant, were you able to get
some suggestions of an efficient solution for passing the entire set of
matched ids to a different process (in abstraction from the discussion
whether it's a desirable solution)?
Cheers,
Jan

scoring and be useful for display, but as i understand it, it is a

example, if we assume situation when we index authors <-- and add
payload to them
field:author | payload [affiliation,field_of_study,email]
------------------------------
ellis | cern,umi hep-theory [email protected]
swank | umi hep-ex [email protected]
is it possible to query this structure directly? ex.
"author:swink~4 and author:affiliation:cern"
(I want to find all names similar to swink, schwink, sink... and i
also know the person is working at cern -- but i am not interested in
a record which was written by swink@umi, and ellis@cern --> i want
only swink@cern and for that i need payload)
The answer to the specific question is no, you can't query the payload
directly.
Suggested alternatives:
* Index the author and the affiliation at the same position. There
should then be a way to query for "swink~4" and "cern" and specify
there must be zero distance between the terms.
* index the author and the affiliation with a delimiter, like "swink_cern",
2)
What would be the best strategy to have several separate indexes? Ie.
to have a separate index for metadata, for recently-changed-metadata,
fulltext, citation-pairs?
presumably, all those indexes contain only records (so the results
from them are mergeable on the recid match), but obviously the scoring
function makes sense only inside the index; but if one would like to
combine results (in a meaningful way) from the several indexes, what
would be the best strategy?
Grant says something called ParallelReader could be used in this case.
I need more time to digest your first answer to the original question.
