Hello Riak Users, We are excited to announce the release of Riak Search version 0.14!
Pre-built installations and source tarballs are available at: http://downloads.basho.com/ Release notes are at (also copied below): https://github.com/basho/riak_search/raw/riak_search-0.14.0/releasenotes/riak_search-0.14.0.txt Thanks, Basho ------------------------------- Riak Search 0.14.0 Release Notes -------------------------------- The majority of effort during development of Riak Search 0.14 went toward rewriting the query parsing and planning system. This fixes all known query planning bugs. We also managed to add quite a few new features and performance improvements. See the highlights below for details. Important Configuration and Interface Changes: - The system now uses the 'whitespace_analyzer_factory' by default. (It previously used the 'default_analyzer_factory', which has been renamed to 'standard_analyzer_factory'.) - Indexing and searching will fail with an error message if the analyzer_factory configuration setting is not set at either a schema or field level. - The method signature for custom Erlang and Javascript extractors has changed. Highlights: - Fixed the query parser to properly respect field-level analyzer settings. - Fixed the query parser to correctly handle escaped special characters and terms within single-quotes and double-quotes. - Fixed the query parser's interpretation of inclusive and exclusive ranges, allowing an inclusive range on one side, and an exclusive range on the other (mimicking Lucene). - Fixed the execution engine to significantly speed up proximity searches and phrase searches. (678) - By default new installations use all Erlang-based extractors, and the JVM is not started. Setting the analysis_port in etc/app.config will cause the JVM to start and allow the use of Java Lucene-based analyzers. - System now aborts queries that would queue up too many documents in a result set. This is controlled by a 'max_search_results' setting in riak_search. Note that this only affects the Solr interface. Searches through the Riak Client API that feed into a Map/Reduce job are still allowed to execute because the system streams those results. - Change handoff of Search data stored in merge_index to be more memory efficient. - Added "*_date", "*_int", "*_text", and "*_txt" dynamic fields to the default schema. ------------ Improvements ------------ 414 - ETS backend now fully functional (415, 795) 592 - Make parser multi-schema aware 783 - Pass Search Props as KeyData to Map/Reduce Query 788 - Add support for indexing Erlang terms / proplists 839 - Create a way to globally clear schema cache 925 - Change search-cmd commands (set_schema, etc.) to use dashes. ---------- Fixed Bugs ---------- 186 - Qilr fails when parsing ISO8601 dates 311 - Qilr does not correctly parse negative numbers 363 - Range queries broken for negative numbers 369 - Range queries broken for ALL integer fields 405 - Update search:index_dir/N to de-index old documents first 411 - Our handling of NOT is different from Solr - "NOT X", "AND NOT X", "AND (NOT X)" 609 - Calling search:search or search:explain with a binary hangs shell 611 - Error in inclusive/exclusive range building 612 - Single term queries shouldn't include proximity clauses 622 - schema and schemachange test fail after new parser 711 - Update new #range operator to support negative integers 729 - Make Qilr use analyzer specified in schema 732 - Word Position is thrown off by Stopwords 764 - The function search:delete_doc/2 blocks if run after search:index_dir/2 797 - Ranges with quoted terms do not return correct results 801 - Anonymous javascript extractors stored in Bucket/Keys validate but are not implemented 802 - Schema allows default field that is not defined, but breaks when analyzing 803 - Cannot use search m/r with riak_client:mapred 832 - Query parser fails on escaped special characters 833 - Proximity searching is currently broken for Whitespace Analyzer 836 - Integer padding is ignored for dynamic fields 837 - The parser interprets hyphens as negations (NOT) 840 - JSON and raw extractors assumes a default field of "value" 849 - Default Erlang Analyzer misses 'that' and 'then' as stop words 850 - text_analyzers module is not tail-recursive 864 - Solr output chokes on dates 885 - Coordinating node exits if result set exceeds available memory 886 - Query parser error when searching on terms that contain the @ symbol 935 - Change merge_index fold to be unordered 956 - Error when setting rs_extractfun through Curl/JSON ------------ Known Issues ------------ 362 - Sorting broken on negative numbers 399 - Handoff can potentially lead to extraneous postings pointing to a missing or changed document 790 - Indexing data too quickly can exhaust the ETS table limit 814 - text_analyzer:default_analyzer_factory skips unicode code points beyond 0x7f 861 - merge_index throws errors when data path contains a period 866 - Sorting positions may change between Solr Searches 867 - Solr "rows" and "start" parameters are applied too early 908 - Solr q.op parameter is ignored (Regression) 955 - Range searching and wildcards across UTF-8 data is broken 957 - Error when viewing bucket properties with a set rs_extractfun
