Dynamic Boosting at query time with boost value as another fieldvalue
Hi all,
I have a specific requirement for query time boosting.
I have to boost a field on the basis of the value returned from one of the
fields of the document.
Basically, I have the creationDate for a document and in order to introduce
recency factor in the search, i need to give a boost to the creation field,
where the boost value is something like a log(1/x) function and x is the
(presentDate - creationDate).
Till now what I have seen is we can give only a static boost to the
documents.
In case you can provide a solution to my problem.. please do reply :)
Thanks a lot,
Regards.
Pooja

Hi,
Will this currentDate work with epoch time only or can work with any date
format as specified by the "simpleDateFormat" class of Java ??
Thank you,
Regards,
Pooja

: ohk.. that means I can't use colon in the fieldname ever in such a scenario
: ?
In most internals, the lucene/solr code base allows *any* character in the
field name, so you *can* use colons in field names, but many of the
"surface" features (like the query parser) treat colon's as special
characters, so in *some* situations colons don't work in field names.

probably we can use colon in fieldname.
are you using the special keyword "_val_" for recip function query?

The colon is used to specify value for a field. E.g. in the query box of
solr admin you would type something like fieldName:<string to search>
(title:Java). You can use hypen '-' or some other character in the field
name instead of colon.

Re: Dynamic Boosting at query time with boost value as another fieldvalue
Posted by Pooja Verlani <po...@gmail.com>.
hi,
Is it possible to have a fieldname with colon for example "source:site"? I
want to apply query time boost as per recency to this field with the recency
function.
Recip function with rord isn't taking my source:site fieldname, its throwing
an exception. I have tried with escape characters too.
Please suggest something.
Thank you,
Regards
Pooja

Take a look at FunctionQuery support in Solr:
