As I know (not 100% sure actually), function queries don't work with

use, you know, some tricky format like
50;40;20 to index multivalued field as single-valued and then parse this
into values list in function.

Hi Kydryavtsev
Thanks a lot it works, but how do i pass a multivalued field values to a
function query?
Can it be passed as a String array?
Thanks Regards

Custom parser should parse this into value sources list. From first two
field sources we can get per doc value for this particular fields,
another
three will be ConstValueSource instances - just constants, so we can
access
all 5 values and implement custom formula per doc id. Find examples in
ValueSourceParser and solr functions like DefFunction or

Hi Hoss,
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
records based on the value of the formula.
The formula has elements from the record.
For eg. for the following document ,I need to apply the formula
(maxprice -
solrprice)/ (maxprice - minprice) + count(cities)/totalcities.
where maxprice, maxprice and total cities will be available at run
time.
So for the following record, it has to execute as (1 -
*5000*)/(1-2000)
+ *2*/5 (where 5000 and 2, which are in bold are from the document)
doc
field name=idapartment_1/field
field name=nameCasa Grande/field
field name=localitychennai/field
field name=localitybangalore/field
field name=price5000/field
/doc
Thanks Regards

You can implement it in this way:
Index number of cities as new int field (like field

customFunction(price, numberOfCities, 1, 2000, 5)
