RSS All releases tagged Minor

  •  25 Jul 2013 00:20

Release Notes: This version includes a new hybrid inverted index/suffix tree indexing scheme that should make calculating search results from future crawls faster (doesn't affect old crawls). It can make use of HTTP ETag: and Expire: information when deciding whether to download a URL it has seen before. It also supports the creation of classifiers using active learning. These can be used to label and add scoring information to documents during a crawl. This release includes improvements to the RSS feed news_updater and a segmenter for Chinese.

Release Notes: This release supports materializing as new indexes query-based combinations (crawl mixes) of old search indexes. This should make query performance of crawl mixes much better. Cache pages of search results now have a new history UI which allows you to search cache pages in all indexes you have, much like the way Internet Archive does. Yioop now supports spell corrections on searches after they have been performed, and it has an API for transliterating between roman and other scripts. Query performance has been improved over previous versions, and lots of minor bugs have been fixed.

Release Notes: This release adds initial support for word suggestions as a user types in queries. The bigramming used to speed common two word queries now works with n word grams. N word gram filter files can now be created using Wikipedia raw page count dumps. This version adds support for * and $ in allowed- and disallowed-to-crawl sites. Using this, the user can crawl sites to a fixed depth. Robots.txt processing now supports * and $ in robot.txt paths. Support for NOSNIPPET, NOARCHIVE, and X-Robots-tag HTTP headers has also been implemented. A tool for editing search summaries after a crawl has also been added.

Release Notes: This release improved scalability by allowing multiple machines to maintain portions of the "to crawl next" queue. Query processing can also be split amongst machines, with different machines being responsible for documents of a given hash. Yioop! now supports mirroring of machines. Two word phrases as determined by an XML file such as Wikipedia URL dump can now be treated as a logical unit. The Yioop! model-view-controller framework has been made easier to extend and documentation for it has been added to the website.

Release Notes: This version supports starting, stopping, and viewing log files of the queue server and fetchers from a Web interface. One can now inject new URLs into an active crawl via a Web interface. This version of Yioop! supports re-crawling of pages after a fixed number of days. Also, the file extensions that are crawled, the number of bytes downloaded per page, and how Yioop! weighs different page components can now all be controlled through a Web interface rather than just the config.php file. Improvements have also been made to how HTML Processor extracts text to index.
