A couple of years back, there was talk in the solr - user forum about a http://lucene.472066.n3.nabble.com/correct-impossible-to-filter-facet-on-ExternalFileField-tt498170.html#a498171 proposed updateable field for an external data store that could affect the filtered results. Field types such as ExternalFileField are useful only in function queries which are good for sorting but not filtering.
If you had to go about implementing such a feature, then how would you do that today? Would you provide your own custom IndexReaderFactory that would know to go to the external data source for any updateable fields in the document? I ask because one of the fields in my schema has a really short shelf live while the rest have relatively long shelf life. I would prefer to enjoy the performance benefits of a long polling interval and would not mind pulling this one field (a boolean) from some external caching system such as ehcache. -- View this message in context: http://lucene.472066.n3.nabble.com/how-would-you-implement-an-updateable-field-circa-2011-tp3566192p3566192.html Sent from the Lucene - Java Developer mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
