Re: math with date and modulo
: I try to get a diff of today and an dateField. from this diff, i want do a : modulo from another field with values of 1,3,6,12 ... : (DIFF(Month of Today - Month of Search) MOD interval) = 0 a) it looks like modulus was never implemneted as a function ... probably overlooked before it has not java.lang.Math.* static? ... please file a bug, it should be fairly trivial to add. b) even with a mod(a,b) function, i'm not sure that you could do whta it seems like you want to do -- the ms() function will easily let you conpute the number of milliseconds between two date field, but there's no fuction that will give you the numeric value for the month of year (or day of month, or hour of day, etc...) for a date field ... even if there was, i don't think your calculation would work when the current month is "before" the month indexed in the date field. If i understand your goal, you are probably better off indexing the month as it's own field (either numericly or just as a simple string) and then computing the list of matches you care about in the client (ie: fq=month:(feb, may, aug, nov) ) -Hoss
math with date and modulo
Hello. i am fighting with the FunctionQuery of Solr. I try to get a diff of today and an dateField. from this diff, i want do a modulo from another field with values of 1,3,6,12 in a function somthing like this. ( i know that some functions are not available in solr) q={!func}$v2=0&v1=(NOW - $var)&v2=modulo($v1,interval) OR (DIFF(Month of Today - Month of Search) MOD interval) = 0 can anybody give me some tipps ? - --- System One Server, 12 GB RAM, 2 Solr Instances, 8 Cores, 1 Core with 45 Million Documents other Cores < 200.000 - Solr1 for Search-Requests - commit every Minute - 5GB Xmx - Solr2 for Update-Request - delta every Minute - 4GB Xmx -- View this message in context: http://lucene.472066.n3.nabble.com/math-with-date-and-modulo-tp3335800p3335800.html Sent from the Solr - User mailing list archive at Nabble.com.
