The beta2 unveils the new scheduler base on the powerful Quartz Scheduler. This feature lets you plan periodic jobs without needing external tools (crontab, task planner, etc.). Each job may contain several tasks. You may start/stop the file or Web crawler, launch a database crawl, optimize the index, or replicate the index on one or more OpenSearchServer instances. The beta2 is stable and already used in production. This release also include some bugfixes.
More than 50 new features and bugfixes were added. An index can be replicated on a remote server. An n-grams filter and a shingle filter provide new possibilities, such as a suggestion box, wrong spelling tolerance, and automated topic generation. A database crawler supporting join queries and external files was added. Several improvements were made to the Web crawler, such as a URL exporter, sub-domain extraction, an exclusion list, manual crawling, and a parameter filter. An API and Web interface for monitoring and supervision was added. The new audio parser offers the ability to index torrent, MP3/MP4, OGG Vorbis, FLAC, and WMA files.
This first developer release is already pretty stable. There are a lot of improvements. The main new features are the possibility to index only the specified content, extracting term frequency informations, a new API to list, create, or modify fields in a specified schema, and secured access with privileges.
This is maintenance release. Statistics are now set up within the templates; no more further configuration is required. Two bugs were fixed: the Web crawler follows disallow directives from robots.txt. It also reads the query part of an URL when evaluating robots.txt.
This is a maintenance release. It has read-only support and some bugfixes. The PHP API no longer fails on some query with incorrect XML characters. This release fixes an issue with statistics aggregation. Sort functionality no longer ignores sort order. A performance issue with large field cache, an issue with the performance of the Web crawler, a negative value on Web crawler statistics, a behavior problem of the wildcard function, and duplication of the returned field in returned XML.
