Hi Yonik Sorry for my late reply. I have been trying to get to the bottom of this but I'm getting inconsistent behaviour. Here's an example:
Query = "pi:rcs100" - Here going to use "pid_rcs" as join value <result name="response" numFound="1" start="0"> <doc> <str name="pi">rcs100</str> <str name="ct">rcs</str> <str name="pid_rcs">G1</str> <str name="name_rcs">Emerging Market Countries</str> <str name="definition_rcs">All business events relating to companies and other issuers of securities.</str> </doc> </result> </response> Query = "code:G1" - See how many docs have "G1" in their code field. Notice that "code" is multi valued - <result name="response" numFound="2" start="0"> - <doc> <str name="ct">cat</str> <date name="maindocdate">2011-04-22T05:48:57Z</date> <str name="pi">nCIF3wGpXk+1029782</str> - <arr name="code"> <str>G1</str> <str>G7U</str> <str>GK</str> <str>ME7</str> <str>ME8</str> <str>MN</str> <str>MR</str> </arr> </doc> - <doc> <str name="ct">cat</str> <date name="maindocdate">2011-04-22T05:48:57Z</date> <str name="pi">nCIF7YcLP+1029782</str> - <arr name="code"> <str>G1</str> <str>G7U</str> <str>GK</str> <str>ME7</str> <str>ME8</str> <str>MN</str> <str>MR</str> </arr> </doc> </result> </response> Now for the join: http://10.15.39.137:8983/solr/file/select?q={!join from=pid_rcs to=code}pi:rcs100 - <result name="response" numFound="3" start="0"> - <doc> <str name="ct">cat</str> <date name="maindocdate">2011-04-22T05:48:57Z</date> <str name="pi">nCIF3wGpXk+1029782</str> - <arr name="code"> <str>G1</str> <str>G7U</str> <str>GK</str> <str>ME7</str> <str>ME8</str> <str>MN</str> <str>MR</str> </arr> </doc> - <doc> <str name="ct">cat</str> <date name="maindocdate">2011-04-22T05:48:57Z</date> <str name="pi">nCIF7YcLP+1029782</str> - <arr name="code"> <str>G1</str> <str>G7U</str> <str>GK</str> <str>ME7</str> <str>ME8</str> <str>MN</str> <str>MR</str> </arr> </doc> - <doc> <str name="ct">cat</str> <date name="maindocdate">2011-04-22T05:48:58Z</date> <str name="pi">nCN1763203+1029782</str> - <arr name="code"> <str>A2</str> <str>A5</str> <str>A9</str> <str>AN</str> <str>B125</str> <str>B126</str> <str>B130</str> <str>BL63</str> <str>G41</str> <str>GK</str> <str>MZ</str> </arr> </doc> </result> </response> So as you can see I get back 3 results when only 2 match the criteria. i.e. docs where G1 is present in multi valued "code" field. Why should the last document be included in the result of the join?

Can you come up with a simple example where you are not getting the expected results? -Yonik http://www.lucidimagination.com This email was sent to you by Thomson Reuters, the global news and information company.
