问题
I have a range function in a Solr fq that works as expected:
{!frange l=1 u=2}sum(termfreq(tags,'twitter'),termfreq(tags,'facebook'),termfreq(tags,'pinterest'))
However, if I try to further refine it by adding an additional parameter to the end:
{!frange l=1 u=2}sum(termfreq(tags,'twitter'),termfreq(tags,'facebook'),termfreq(tags,'pinterest')) AND (region:"US")
I get the error: org.apache.solr.search.SyntaxError: Unexpected text after function: AND (region:"US")
If I try to prepend an additional parameter:
(region:"US") AND {!frange l=1 u=2}sum(termfreq(tags,'twitter'),termfreq(tags,'facebook'),termfreq(tags,'pinterest'))
I get the error: org.apache.solr.search.SyntaxError: Expected ')' at position 27 in 'sum(termfreq(tags,'twitter''
I've tried wrapping the range portion in additional parenthesis but still having no luck. How can I combine a range function with additional query parameters?
回答1:
Ok I got solved what I need to. Basically, I was running commands from the Solr admin dashboard. Although I wasn't able to mix the frange command above with other queries in fq, I was able to put my frange command in q and keep the other queries in fq.
q: {!frange l=1 u=2}sum(termfreq(tags,'twitter'),termfreq(tags,'facebook'),termfreq(tags,'pinterest'))
fq: (region:"US")
I answered a similar question here.
My issue is solved, but I'll leave this unanswered for a few days in case someone knows of a better way.

Please check my answer here: Nested functional range query with OR
which solves this problem using query solr feature.

You can also keep adding fq= parameters this is seen as an AND, for example:
&fq={!frange l=1 u=2}sum(termfreq(tags,'twitter'),termfreq(tags,'facebook'),termfreq(tags,'pinterest'))&fq=region:"US"
