Dear list, hope somebody can help me understand/avoid this. I am sending an "add" request with allowDuplicates=false to a Solr 1.4.1 instance. This is for debugging purposes, so I am sending the exact same data that are already stored in Solr's index. I am using the PHP PECL libraries, which fail completely in giving me any hint on what goes wrong.
Only sending the same "add" request again gives me a proper "SolrClientException" that hints: ERROR: [288400] multiple values encountered for non multiValued field "field2" [fieldvalue, fieldvalue] The scenario: - "field1" is implicitly single value, type "text", indexed and stored - "field2" is generated via a copyField directive in schema.xml, implicitly single value, type "string", indexed and stored What appears to happen: - On the first "add" (SolrClient::addDocuments(array(SolrInputDocument theDocument))), regular fields like "field1" get overwritten as intended - "field2", defined with a copyField, but still single value, gets _appended_ instead - When I retrieve the updated document in a query and try to add it again, it won't let me because of the inconsistent multi-value state - The PECL library, in addition, appears to hit some internal exception (that it doesn't handle properly) when encountering multiple values for a single value field. That gives me zero results querying a set that includes the document via PHP, while the document can be retrieved properly, though in inconsistent state, any other way. But: Solr appears to be generating the corrupted state itsself via copyField? What's going wrong? I'm pretty confused... Thank you, Alex
