I am very excited to announce the availability of Solr 4.3 with
RankingAlgorithm40 1.4.8 with realtime-search with multiple
granularities. realtime-search is very fast NRT and allows you to not
only lookup a document by id but also allows you to search in realtime,
see http://tgels.org/realtime-nrt.jsp. The update performance is about
70,000 docs / sec. The query performance is in ms, allows you to query
a 10m wikipedia index (complete index) in <50 ms.
This release includes realtime-search with multiple granularities,
request/intra-request. The granularity attribute controls the NRT
behavior. With attribute granularity="request", all search components
like search, faceting, highlighting, etc. will see a consistent view of
the index and will all report the same number of documents. With
granularity="intrarequest", the components may each report the most
recent changes to the index. realtime-search has been contributed back
to Apache Solr, see https://issues.apache.org/jira/browse/SOLR-3816.
RankingAlgorithm 1.4.8 supports the entire Lucene Query Syntax, ± and/or
boolean/dismax/glob/regular expression/wildcard/fuzzy/prefix/suffix
queries with boosting, etc. and is compatible with the lucene 4.3 api.
You can get more information about realtime-search performance from here:
