4.0.0 there is a new softcommit feature which implements a near-real-time (NRT) search option. The softcommit does not do IO and does not cause performance issues. YaCy has now an extension in its solr connectors to use the softcommit feature. The softcommit call now replaces all places where a hard commit was used. Furthermore the commit strategy in when doing a search from the web interface was changed (it's done every time before a search is done). The softcommit feature was implemented because it was needed for the following changes (customer demands), which is also included in this git commit: - added a feature to identify all documents which have unique titles and/or unique descriptions. These unique flags are disabled by default. - added also a feature to set a flag when the url from a canonical tag is equal to the document url. This is also disabled by default. To support the new softcommit strategy, the commitWithinMs option was set to -1 do disable automatic commit based on document insert times. If documents are inserted permanently then also a commit would happen permanently whenever the commitWithinMs time is reached. This would conflict with the regular autocommit of 10 minutes and the new softcommit strategy. |
