It is not clear whether your observation of increased response time is due to many hits or faceting in itself. - How many fields are you faceting on? - How many unique values does your facet fields have (approximately)? - What is the content of your facets (Strings, numbers?) - Which facet.method do you use? - What is the response time with faceting and a few thousand hits? > Do you have some advice on how improve the facet performance when hit > many documents. That depends on whether your bottleneck is the hitcount itself, the number of unique facet values or something third like I/O. - Toke Eskildsen, State and University Library, Denmark --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
