When a 'regex' is specified in addition to a 'dir', only the files in that directory which completely match the regex (anchored on both ends) will be included. If a 'dir' option (with or without a regex) is used and nothing is found that matches, a warning will be logged.

"numVersionBuckets" - sets the number of buckets used to keep track of max version values when checking for re-ordered updates; increase this value to reduce the cost of synchronizing access to version buckets during high-volume indexing, this requires 8 bytes (long) * numVersionBuckets of heap space per Solr core. --> <updateLog> <str name="dir">${solr.ulog.dir:}</str> <int name="numVersionBuckets">${solr.ulog.numVersionBuckets:65536}</int> </updateLog> <!-- AutoCommit Perform a hard commit automatically under certain conditions.

FastLRUCache has faster gets and slower puts in single threaded operation and thus is generally faster than LRUCache when the hit ratio of the cache is high (> 75%), and may be faster under other scenarios on multi-cpu systems. --> <!-- Filter Cache Cache used by SolrIndexSearcher for filters (DocSets), unordered sets of *all* documents that match a query. When a new searcher is opened, its caches may be prepopulated or "autowarmed" using data from caches in the old searcher. autowarmCount is the number of items to prepopulate. For LRUCache, the autowarmed items will be the most recently accessed items. Parameters: class - the SolrCache implementation LRUCache or (LRUCache or FastLRUCache) size - the maximum number of entries in the cache initialSize - the initial capacity (number of entries) of the cache. (see java.util.HashMap) autowarmCount - the number of entries to prepopulate from and old cache. maxRamMB - the maximum amount of RAM (in MB) that this cache is allowed to occupy.

When a search is requested, a superset of the requested number of document ids are collected.
