Hi, Thank you for your answer. Is it something that is somehow theoretically quantifiable, or the only way to quantify the overhead is to prototype and to benchmark? Regards, Aurelien On 28.07.2015 17:15, Uwe Schindler wrote: It depends on the number of fields. If you search on 3 fields it

It depends on the number of fields. If you search on 3 fields it is not likely to be a problem (the general use case 3 fields: plain, stemmed, folded). But if you have like 50 fields, the slow down is likely very large! - Uwe Schindler H.-H.-Meier-Allee 63, D-28213 Bremen http://www.thetaphi

Performance impact of searching across multiple fields

Hi, I am wondering about the real performance impact of searching across multiple fields instead of using a catch-all field. I know that Lucene is optimized to do that and that there are mechanisms to mitigate the overhead but does anybody know if there are performance benchmarks related to

Can we skip matching lucene document by using custom collector or some other way. Like I want to bring all document created by user xxx on specific date but after we got a match, we want to run some logic which figure out either the document is acceptable or not. We cannot specify criteria in lucen
