Re: Passing variables as values in Query Filter
Hi Ahmet,
Thanks a lot
What I need is this .
q={!lucene df=city v=$qq}qq=customfunc(x)
In this case,
qq=custfunc(x) -- where custfunc is a custom function that has to be
executed. Instead, how it acts now is, it takes it as a string to search
if qq is a number, you will get a NumberFormatException

Thanks a lot for your response. The actual problem is,
For every record that I query, I have to execute a formula and sort
the

The formula has elements from the record.
For eg. for the following document ,I need to apply the formula
(maxprice -

where maxprice, maxprice and total cities will be available at run
time.
So for the following record, it has to execute as (1 -

XY Problem
Your question appears to be an XY Problem ... that is: you are dealing
with X, you are assuming Y will help you, and you are asking about Y
without giving more details about the X so that we can understand the
full issue. Perhaps the best solution doesn't involve Y at all?

: Subject: Getting Solr Document Attributes from a Custom Function
:
: Hi All,
:
: I have a written a custom solr function and I would like to read a
property
: of the document inside my custom function. Is it possible to get that
using
: Solr?
:
: For eg. inside the floatVal method, I would like to get the value of the
: attribute name
:
: public class CustomValueSource extends ValueSource {
:
: @Override
: public FunctionValues getValues(Map context,
: AtomicReaderContext readerContext) throws IOException {
: return new FloatDocValues(this) { @Override public float floatVal(int
doc)
: {
: /***
: getDocument(doc).getAttribute(name)
:
: / }}}
:
: Thanks Regards
