I remember myself doing &rows=2147483647 2,147,483,647 is integer’s maximum value. I recall using a number bigger than that once and having a NumberFormatException because it couldn’t be parsed into an int. I don’t know if they use Long nowadays, but 2 billion rows is normally more than enough. Small note: Be careful if you are … Read more
Since Solr 1.3, there’s been decent multi-core search capabilities in Solr. Please read the Distributed Search article where it explains how to use the shards parameter to query across multiple cores and return results as one data set.
Use – to indicate NOT. For example, to query documents with id not starting with A59, the query would be: -id:A59*, that is: /solr/select/?q=-id:A59* To delete by query, post the query in a delete message to the update handler, as specified here. EDIT: NOT (all uppercase) can also be used as boolean operator
It’s preferable to use Filter Query over normal Query wherever possible. FilterQuery is able to take advantage of the FilterCache, which would be a huge performance boost in comparison to your queries.
The solution from Mauricio Scheffer worked for me until I’ve included it into full query. The query itself may contain up to three fields with ranges and somewhere in the middle Solr failed to process it. I have managed to solve it with next query: (myfield:[start TO finish] OR (*:* NOT myfield:[* TO *])) It … Read more
How is your itemtype field analysed? If it is of type string , then use: fq=itemtype:”Supply Chain Intermediaries” Otherwise you can also try: fq=itemtype:(Supply Chain Intermediaries) Assuming OR is the default operator in your config and text is the default search field, your query will get translated to: fq=itemtype:Supply OR text:(Chain Intermediaries) Chain and Intermediaries … Read more
Go to the solr folder and Do this.. bin/solr delete -c collection_name and restart solr with bin/solr restart
The canonical way is this: fieldName:[* TO *] Using a ” on the left side as Paige Cook suggested will probably work too but I don’t trust it as much as I do the above. And since this is to a Location field, you will probably have to do this against one of the two … Read more
Remove the AddSchemaFieldsUpdateProcessorFactory section from the updateRequestProcessorChain config in your solrconfig.xml The schemaFactory option in solrconfig.xml. This controls whether the Schema should be defined as a “managed index schema”: schema modification is only possible through the Schema API. By default, if no schemaFactory is specified, then the default behavior is to use the “ClassicIndexSchemaFactory” The … Read more
I’ve gotten the same error: HTTP ERROR: 404 missing core name in path In my case I’ve forgotten so set the solr/home value in the WEB-INF/web.xml file <env-entry> <env-entry-name>solr/home</env-entry-name> <env-entry-value>/put/your/solr/home/here</env-entry-value> <env-entry-type>java.lang.String</env-entry-type> </env-entry> After I’ve added the above code and restarted the server, the error was gone.
