ravendb - Searching by Entity Name and Last Modified Date -


i have number of commands stored in ravendb , implement icommand. want able search on metadata of last modified , raven-entity-name. doing multi map on each command below:

public class commandauditsearch_index : abstractmultimapindexcreationtask<commandauditsearch_index.results>     {         public class results         {             public string commandtype { get; set; }             public datetime lastmodified { get; set; }         }          public commandauditsearch_index()         {             addmap<newemployeestartcommand>(employees => employees.select(x => new             {                 commandtype = metadatafor(x).value<string>("raven-entity-name"),                 lastmodified = metadatafor(x).value<datetime>("last-modified")             }));              addmap<employeeleavercommand>(employees => employees.select(x => new             {                 commandtype = metadatafor(x).value<string>("raven-entity-name"),                 lastmodified = metadatafor(x).value<datetime>("last-modified")             }));              index(results => results.commandtype, fieldindexing.analyzed);         }     }

i query follows:

session.query<commandauditsearch_index.results, commandauditsearch_index>()                               .where(x => x.commandtype == commandtype && x.lastmodified >= datetime.today).oftype<icommand>().tolist();

i know there index built raven tag (entity name) , last modified date cant seem figure out how results index above gives me.

can point me in right direction of static index don't have have multi maps above each command have query gives me results list of icommands?

thanks

a couple of points:

  • you don't need mark field analyzed unless going doing fulltext searching search query method. if using where, there no advantage analyzing index term.

  • if looking metadata values in results, need them metadata instead of document data using getmetadatafor. reference here.

  • as said, there's index need. easiest way query using lucenequery api.

    var tag = documentstore.conventions.gettypetagname(thecommand.gettype());  var results = session.advanced                      .lucenequery<icommand, ravendocumentsbyentityname>()                      .whereequals("tag", tag)                      .andalso()                      .wheregreaterthanorequal("lastmodified", datetime.today                                                           .touniversaltime())                      .tolist();  foreach (var result in results) {     var md = session.advanced.getmetadatafor(result);     var entityname = md.value<string>("raven-entity-name");     var lastmodified = md.value<datetime>("last-modified");      // can see metadata if     debug.writeline(md.tostring(formatting.indented)); }

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...

(and yes disable button when user clicks submit button). unicorn 4.8.2 ruby 1.9.3 rails 3.2.14 any great! thanks! although may not fix problem, upgrade ruby 2.0.0. there blog mentioning idea upgrade ruby 2.0.0 if using unicorn. for example: https://www.digitalocean.com/community/articles/how-to-optimize-unicorn-workers-in-a-ruby-on-rails-app specifically: if using ruby 1.9, ...
