Hello, What we have done is created multiple solr instances on the same server, where each instance is created with the DataImportHandler from a different DB. The information on each DB is similar, so the schema's for each instance are pretty much the same. Our goal is to use the shards feature to combine the results into a single table.
The problem is that when we use shards, the "numFound" is acting very strangely. Here are some examples: 2 solr instances: localhost:8080/alpha/ localhost:8080/bravo/ Lets say i'm searching for the term "fred". If I do: localhost:8080/alpha/select?q=fred&rows=10&start=0 I get numFound="0". That's fine localhost:8080/bravo/select?q=fred&rows=10&start=0 I get: <result name="response" numFound="27" start="0"> Followed by 10 <doc></doc>'s. This is also fine. When i do these [same result for both]: localhost:8080/alpha/select?q=fred&rows=10&start=0&shards=localhost:8080/alpha,localhost:8080/bravo localhost:8080/bravo/select?q=fred&rows=10&start=0&shards=localhost:8080/alpha,localhost:8080/bravo I get: <result name="response" numFound="18" start="0"> followed by 1 <doc></doc> So... something weird happened... There should be 27 results, but even if it thought there were only 18 results, it should have displayed 10 of them. Alright, so I tried: localhost:8080/alpha/select?q=fred&rows=1&start=0&shards=localhost:8080/alpha,localhost:8080/bravo localhost:8080/bravo/select?q=fred&rows=1&start=0&shards=localhost:8080/alpha,localhost:8080/bravo I got: <result name="response" numFound="27" start="0"> followed by 1 <doc></doc> Seems to be working alright with this... But lets try... localhost:8080/alpha/select?q=fred&rows=1&start=1&shards=localhost:8080/alpha,localhost:8080/bravo localhost:8080/bravo/select?q=fred&rows=1&start=1&shards=localhost:8080/alpha,localhost:8080/bravo I got: <result name="response" numFound="26" start="1"> with no <doc></doc>'s... wtf? I continued this up to start=10, and numFound decreased by 1 every time, with no more <doc></doc>'s. So i changed it to rows=100&start=0 and i got: <result name="response" numFound="2" start="0"> followed by 2 <doc></doc>'s. This issue is happening with multiple search queries, however with some other search queries, it works fine and returns the proper number for numFound, and however many <doc>'s there are supposed to be. Has anyone seen this issue before? -- View this message in context: http://www.nabble.com/Solr-Shard---Strange-results-tp23561201p23561201.html Sent from the Solr - User mailing list archive at Nabble.com.
