Specifying `async=<request-id>` enables you to make an asynchronous call, the status of which can be requested using the <<requeststatus,REQUESTSTATUS>> call at any time.
 
 As of now, REQUESTSTATUS does not automatically clean up the tracking data structures, meaning the status of completed or failed tasks stays stored in ZooKeeper unless cleared manually. DELETESTATUS can be used to clear the stored statuses. However, there is a limit of 10,000 on the number of async call responses stored in a cluster.

 Every core watches the ZooKeeper directory for the configset being used with that core. In standalone mode, however, there is no watch (because ZooKeeper is not running). If there are multiple cores in the same node using the same configset, only one ZooKeeper watch is used. For instance, if the configset 'myconf' is used by a core, the node would watch `/configs/myconf`. Every write operation performed through the API would 'touch' the directory (sets an empty byte[] to trigger watches) and all watchers are notified. Every core would check if the Schema file, `solrconfig.xml` or `configoverlay.json` is modified by comparing the `znode` versions and if modified, the core is reloaded.
 
 If `params.json` is modified, the params object is just updated without a core reload (see the section <<request-parameters-api.adoc#request-parameters-api,Request Parameters API>> for more information about `params.json`).

 == Substituting Properties in Solr Config Files
 
 Solr supports variable substitution of property values in config files, which allows runtime specification of various configuration options in `solrconfig.xml`. The syntax is `${propertyname[:option default value]`}. This allows defining a default that can be overridden when Solr is launched. If a default value is not specified, then the property _must_ be specified at runtime or the configuration file will generate an error when parsed.
 
 There are multiple methods for specifying properties that can be used in configuration files. Of those below, strongly consider "config overlay" as the preferred approach, as it stays local to the config set and because it's easy to modify.

+=== CDCR Limitations
 
 The current design of CDCR has some limitations. CDCR will continue to evolve over time and many of these limitations will be addressed. Among them are:
 
 * CDCR is unlikely to be satisfactory for bulk-load situations where the update rate is high, especially if the bandwidth between the Source and target clusters is restricted. In this scenario, the initial bulk load should be performed, the Source and target data centers synchronized and CDCR be utilized for incremental updates.
 * CDCR is currently only active-passive; data is pushed from the Source cluster to the target cluster. There is active work being done in this area in the 6x code line to remove this limitation.
 * CDCR works most robustly with the same number of shards in the Source and target collection. The shards in the two collections may have different numbers of replicas.

 == Avoiding Distributed Deadlock
 
 Each shard serves top-level query requests and then makes sub-requests to all of the other shards. Care should be taken to ensure that the max number of threads serving HTTP requests is greater than the possible number of requests from both top-level clients and other shards. If this is not the case, the configuration may result in a distributed deadlock.
 
 For example, a deadlock might occur in the case of two shards, each with just a single thread to service HTTP requests. Both threads could receive a top-level request concurrently, and make sub-requests to each other. Because there are no more remaining threads to service requests, the incoming requests will be blocked until the other pending requests are finished, but they will not finish since they are waiting for the sub-requests. By ensuring that Solr is configured to handle a sufficient number of threads, you can avoid deadlock situations like this.
 
-[[DistributedRequests-PreferLocalShards]]
-== Prefer Local Shards
+== preferLocalShards Parameter
 
 Solr allows you to pass an optional boolean parameter named `preferLocalShards` to indicate that a distributed query should prefer local replicas of a shard when available. In other words, if a query includes `preferLocalShards=true`, then the query controller will look for local replicas to service the query instead of selecting replicas at random from across the cluster. This is useful when a query requests many fields or large fields to be returned per document because it avoids moving large amounts of data over the network when it is available locally. In addition, this feature can be useful for minimizing the impact of a problematic replica with degraded performance, as it reduces the likelihood that the degraded replica will be hit by other healthy replicas.

 When not using SolrCloud, it is up to you to get all your documents indexed on each shard of your server farm. Solr supports distributed indexing (routing) in its true form only in the SolrCloud mode.
 
 In the legacy distributed mode, Solr does not calculate universal term/doc frequencies. For most large-scale implementations, it is not likely to matter that Solr calculates TF/IDF at the shard level. However, if your collection is heavily skewed in its distribution across servers, you may find misleading relevancy results in your searches. In general, it is probably best to randomly distribute documents to your shards.

 == Cycle Detection
 
 The `nodes` function performs cycle detection across the entire traversal. This ensures that nodes that have already been visited are not traversed again. Cycle detection is important for both limiting the size of traversals and gathering accurate aggregations. Without cycle detection the size of the traversal could grow exponentially with each hop in the traversal. With cycle detection only new nodes encountered are traversed.
 
 Cycle detection *does not* cross collection boundaries. This is because internally the collection name is part of the node ID. For example the node ID "\johndoe@apache.org", is really `emails/johndoe@apache.org`. When traversing to another collection "\johndoe@apache.org" will be traversed.

The ranked co-occurrence counts provide candidates for a recommendation. The `scoreNodes` function can be used to score the candidates to find the best recommendation.
 
 Before diving into the syntax of the `scoreNodes` function it's useful to understand why the raw co-occurrence counts may not produce the best recommendation. The reason is that raw co-occurrence counts favor items that occur frequently across all baskets. A better recommendation would find the product that has the most significant relationship with productID ABC. The `scoreNodes` function uses a term frequency-inverse document frequency (TF-IDF) algorithm to find the most significant relationship.

 Performance is sensitive to the number of unique terms that are associated with a pattern. For instance, searching for "a*" will form a large OR clause (technically a SpanOr with many terms) for all of the terms in your index for the indicated field that start with the single letter 'a'. It may be prudent to restrict wildcards to at least two or preferably three letters as a prefix. Allowing very short prefixes may result in to many low-quality documents being returned.
