Nested functional range query with OR

问题

I'm trying to do a functional query with an OR/AND however it seems there are limitations in doing so. Here is the logic for the SQL equivalent of the query I'm trying to perform:

ABS(col1-:val1)<1 OR (col1 IS NULL AND ABS(col2-:val1)<1)

Here is my current working fq query to grab the the documents with an ABS difference of <1.

fq={!frange l=0 u=1}abs(sub(col1,val1))

Here is what I'm trying to execute but can't without error

fq={!frange l=0 u=1}abs(sub(col1,val1)) OR (-col1:[* TO *] AND {!frange l=0 u=1}abs(sub(col2,val1)))

It seems like it's not possible to use and AND or and OR in the same fq when using a functional query. How would I go about doing this? I am using solr 4.1. Thanks

Try

fq={!frange l=0 u=1 v=$myabs}&myabs=abs(sub(col1,val1))

I stumbled upon similar issue and found out the solution. Posting it here so it might help somebody. The original query can be modified like this using query:"..." feature of solr:

fq=_query_:"{!frange l=0 u=1}abs(sub(col1,val1))" OR (-col1:[* TO *] AND _query_:"{!frange l=0 u=1}abs(sub(col2,val1)))"
