generate field name in query

Hi - is it possible to create a query (or fq) which generates the field to search on, based on whether or not the document has that field?

Eg. Search for documents with prices in the range 100 - 200, using either the field "price_owner_float" or "price_customer_float" (if a document has a field "price_owner_float" then use that, otherwise use the field "price_customer_float").

This gives a syntax error:
fq=if(exists(price_owner_float),price_owner_float,price_customer_float):[100 TO 200]

Thanks,
Peter

You should be able to just use
price_owner_float:[100 TO 200]  OR price_customer_float:[100 TO 200]

If the document doesn't have the field the condition is false.

Thanks, but I don't really think a general copy-field is what I want. I want
to specifically search for particular values in named fields.

For example:
if the document has a "field1" then use "field1:[1 TO 100]"; but if there is
no "field1", then check if there is a "field2"; if there is a "field2" then
use "field2:[1 TO 100]; but if there is no "field2", then use "field3:[1 TO
100].

Something like:
?q=*:*&fq=if(exists(field1),field1:[1 TO 100],if(exists(field2),field2:[1 TO
100], field3:[1 TO 100]))


But is this does not work.
Is it even possible?

The common setup is to use copyfield from all your fields into a 'grab bag' containing everything, and then to search on it alone. Cheers -- Rick
