Removed jar files whose licenses do not permit + redistribution by Apache. Disabled compilation of plugins which + require these libraries. (Doug Cutting 20050301) + + 6. Index host and title in separate fields. Host was indexed + previously only as a part of the URL. Title was indexed as an + anchor. Now boosts for matching these fields may be adjusted + separately from boosts for matching anchors and url. Also: move + site indexing to index-basic plugin to minimize the number of + times the URL needs to be parsed; and, stop using anchor analyzer + for anything but anchors. (Piotr Kosiorowski via Doug Cutting + 20050323) + + 7. Add servlet Cached.java that serves cached Content of any mime type. + Slightly modified are web.xml and cached.jsp. + (John Xing, 20050401) + + 8. Add skipCompressedByteArray() to WritableUtils.java. + (John Xing, 20050402) + + 9. Fixes to jsp and static web pages.

Bug #32. + (Jerome Charron via cutting, 20050404) + +10. Added some features to DistributedSearch: new segments can be added + to searchservers without restarting the frontend, defective search + servers are not queried until tey come back online, watchdog keeps + an eye for your searchservers and writes simple statistics. + (Sami Siren, 20050407) + +11. Fix for bug #4 - Unbalanced quote in query eats all resources. + (Piotr Kosiorowski, Sami Siren, 20050407) + +12. Close Issue #33 - MIME content type detector (using magic char sequences). + (Jerome Charron and Hari Kodungallur via John Xing, 20050416) + +13. Add a servlet that implements A9's OpenSearch RSS web service. + (cutting, 20050418) + +14. Remove references to link analysis from tutorial, and enable + scoring by link count when generating fetchlists and searching. + (cutting, 20040419) + +15. Make query boosts for host, title, anchor and phrase matches + configurable. (Piotr Kosiorowski via cutting, 20050419) + +16. Add support for sorting search results and search-time deduping by + fields other than site. + +17. Automatically convert range queries into cached range filters. + This improves the performance and scalability of, e.g., date range + searching. +
