The Collections page provides information about all of the collections running on this server.
If you are running LucidWorks in SolrCloud mode, you will see Cluster Nodes displayed across the top (see screenshot at right). This shows the state of each node in the SolrCloud cluster, including the server hostname and port. A green checkmark indicates that the node is live. Under this, the path to the API for each node is displayed, and clicking on the clipboard icon on the right will copy the URL. The API for the nodes may be useful if you need to check any collection statistics on a specific node.
Under the API path, each collection is listed with an indication of the shard ID for the collection. In this sense, the LucidWorks Search collections matches the concept of the "core" in Solr. A blue box next to each collection/shard on the list indicates if the node is considered a leader.
If you are not running in SolrCloud mode, the Cluster Nodes section will not be displayed. Instead, an Activity graph shows the queries per second for the last hour, day or week; click the links on the right of the graph to change the values.
(Customers using prior versions will notice that Resource Usage has been removed.)
Under the Activity graph, the Collections panel lists each collection, the size of the index in Kb, the number of documents indexed, and how many data sources are configured. Buttons to the right allow you to search the collection or delete it.
Under this is a graph showing query activity over the past month. Click on a collection name to configure data sources or change settings.
Click Create New Collection to create a new collection. The screen shows a form to enter a name for the collection and the option to choose a template to use as the basis for configuration files in the new collection.
Collection templates are a way to save customized schema, synonyms, or other configuration details from one collection and use it in the creation of a new collection (for example, if you know you always need to remove certain fields from the default schema, that can be done in one collection, saved as a template and used to create new collections in the future). For more about how to create a template, see Using Collection Templates.
|Creating Collections with SolrCloud|
If working with SolrCloud enabled, you will see another parameter when creating collections to specify the Number of shards. This will configure LucidWorks to split the index across the number of shards specified. This number should match the number of instances running, but that is not required (because you could start more instances later). See also the section on Using SolrCloud in LucidWorks for more information.
