Can RavenDB faceted search somehow break down a facet into sub-facets? -


i pretty new faceted search, kind of difficult me wrap head around this... here goes:

pretend have item contains collection of subitems , subitem has enum indicates status - have enabled faceted search on categories on both item , subitem using index definition:

public class facetindexitems : abstractindexcreationtask<item> {     public const string facetid = "facets/items";     public const string itemcategoryfacetname = "category";     public const string subitemcategoryfacetname = "subitems_category";      public facetindexitems()     {         map = items => item in items                        subitem in item.subitems                        select new                                   {                                       category = item.category,                                       subitems_category = subitem.category                                   };     } }

and facetsetup:

new facetsetup {     id = facetindexitems.facetid,     facets =         {             new facet {name = facetindexitems.itemcategoryfacetname},             new facet {name = facetindexitems.subitemcategoryfacetname}         } }

so far, good!

now, pretend subitem has status property - there way divide result of each facet different statuses?

e.g. quering data:

{     category: "wut",      subitems: [        {category: "bim", status: "good"},        {category: "bim", status: "good"},        {category: "bim", status: "bad"}     ] }

by item.category.in("wut") && item.subitems.any(s => s.category.in("bim")) yield result like

{     category: {         "good": 2         "bad": 1     },     subitems_category: {         "good": 2         "bad": 1     } }

i unsure whether possible faceted search, , open alternatives if approach wrong.

you have generate different values each option, can't facet on more 1 field @ time. can generate fields @ indexing time, same thing.

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
