Is there a consise way to query just a single field from a solr query?
I was trying to use solr in a BI application which will allow the dynamic creation of olap cubes based on the results of keyword searches; and in this case I'm not really interested in just the top N results nor the documents themsleves; but rather just the complete list of IDs that match. With the queries I know how to write, I get responses like this: ========================================================= <?xml version='1.0' encoding='UTF-8'?><response> <responseHeader><status>0</status><QTime>0</QTime></responseHeader> <result numFound='64737' start='0'> <doc> <str name='id'>644960</str> </doc> <doc> <str name='id'>13</str> </doc> .............. and 200,000 or so more lines.......... </result> </response> ========================================================= I was extremely pleased to see that Solr itself seems fast enough to be useful, but found that I'm spending a dissapointing amount of time sending the results through an XML parser that's surely overkill for this task. Are there any options where I could get a result that looks something like ========================================================= <?xml version='1.0' encoding='UTF-8'?><response> <responseHeader><status>0</status><QTime>0</QTime></responseHeader> <result numFound='64737' start='0'> <doc_ids> 644960 13 8357 66772 193162 .... ..... and 60,000 or so more numbers separated by whitespace..... </doc_ids> </result> </response> ========================================================= Or should I be looking for an altogether different way of approaching things?
